Head of Departments Statement
The Physics Department has continued to thrive during 2013-14 and inside you
will find an overview over the past two years across the considerable breadth of
our activities. I took over as Head of Department in May 2014 from Jo Haigh
and want to thank Jo on behalf of the department for her outstanding leadership
which has left the department in fantastic shape going forward.
The department thrives as an environment where we can provide outstanding
teaching delivered by world class researchers. We also have a mission to
engage the public with the excitement of our work to try and encourage the next

generation of physicists.
Head of the Department of Physics
Inside this report you will find an overview of the world leading research, which is going on within the nine research
groups in the department. You will find a description of the activities of the staff members as well as a listing of a
few of their key publications during this period. We have also listed the research grants which the department has
received and which enable us to carry out our work, as well as the many awards and prizes which members of staff
have received.
We teach around 840 undergraduates and around 400 postgraduate students. Inside you will find an overview of
our undergraduate programmes as well as an indication of the many destinations where our undergraduate students continue after graduation. We were also delighted to introduce summer student exchanges with MIT, UBC,
SNU, and KAIST allowing some of our top undergraduates to gain research experience overseas.
Postgraduate degrees are available as both taught Masters programmes as well as PhD programmes. You will find
inside an overview of the degree courses as well as the topics of projects for the degrees which were awarded
during the period of this review. Our Centres for Doctoral Training (CDTs) have been a real success and allowed
us to provide a great training programme across these multi-disciplinary centres. In addition, the report provides a
summary of the destinations for our PG students. We have continued to provide opportunities for our students to
interact with commercial partners through our Industry Club, and a particularly successful event is the annual postgraduate research symposium.
Outreach remains an important fundamental part of our mission and as part of this we were delighted to sponsor an
artist in residence some of whose work you will find inside the report.
The department renewed its Athena SWAN silver award in 2012, and immediately began planning as to apply for
an upgrade to a gold award. This involves representatives from across the department on our JUNO committee
looking at how we can improve the workplace environment and improve the gender and racial imbalance in physics
We have also been working to keep our graduates in contact with the work which is going on here by sponsoring
events inviting alumni into the department to hear about our research.
The report inside will give you a sense of the strength of the department, which remains one of the top destinations
worldwide for research in and studying physics, and which is in an excellent position to continue to attract the best
and brightest students and researchers.

Department of Physics Review 2013 -14
In October 2013 we welcomed
250 new students, making the
total number of undergraduates
844, one of the largest Physics
departments in the country. This
was the second cohort in which
home students were paying fees
of £9000 per annum. Students
are enrolled onto one of six
programmes leading to an MSci
or BSc degree. Transfers are
easy between most of the
programmes in the early years.
All three of our MSci degrees are
four-year programmes. The MSci
in Physics is by far the most
popular, while Physics with a
Year in Europe and Physics with
Theoretical Physics supply more
specialist needs.
We offer three-year BSc
programmes in Physics and in
Physics with Theoretical Physics.
The four-year BSc in Physics and
Music Performance, offered
jointly with the Royal College of
Music, is unique, and attracts
small numbers of exceptional
candidates. In the summer of
2014 the second cohort of
students graduated on our new
BSc in Physics with Science
Education, offered jointly with
Canterbury Christ Church
University, which gives students
a Physics degree as well as a
teaching qualification in 3 years.
From October 2015 we will also
offer a 4 year MSci version of this
would like it to be is higher than
the national average. Many of
our exceptional overseas
students are female.
The basic structure of the degree
programmes is two years of core
physics and mathematics,
followed by one or two years of
advanced options in selected
areas of physics.
All students, including those on
theoretical physics degrees, do
about 6 hours/week of laboratory
work during the first 2 years.
All programmes include a
research project. Many students
find that the project is the most
Typically 12% of new students
register for BSc degrees and the enjoyable part of their degree as
they are then able to get to grips
remainder for MSci. Just over
24% of our students are women, with a topic that may be at the
which although short of where we frontier of research.
Department of Physics Review 2013 -14
In the third year students can choose from a wide
range of physics options and can also take a
Humanities or Business School course. Students
on the MSci degrees take advanced physics
options in their final year, alongside their major
research project.
Changes to our lecture courses are made regularly
to ensure that they remain topical, but from
October 2012 we have been rolling out a revised
We understand that arriving in a class of 250
students can be daunting and impersonal, so
alongside the lectures we have activities where
students meet in smaller groups and are able to
get to know each other better. Each student is a
member of a group of about 20, who meet
regularly for tutorials as well as laboratory and
professional skills sessions. Two members of the
academic staff are associated with each group and
act as personal tutors, remaining with the group
throughout their time at Imperial. On each course
in years 1 and 2 students have a tutorial each
week in addition to lectures. Tutors encourage
discussion about other topics within physics to help
students see the wider relevance of their studies.
We have exchange agreements with 14
universities in western Europe. In 2013, 24
students went abroad for a full year in Europe
programme and we welcomed 35 visiting students
to the department.
Introduced for the first time in 2012, we have
begun to set up an overseas summer research
project scheme for under-graduate students in
their third year who are on a four year integrated
Masters degree. The project is eight weeks in
length and fully funded through the international
office, the Blackett Laboratory industry club on

International summer research exchange scheme for undergraduate students
Introduced for the first time in 2012,
the international summer research
project exchange scheme for
undergraduate students is designed
to exchange students with some of
our closely linked partner
universities overseas. The
exchange means that we also host
students for the summer from MIT
Boston, the University of Vancouver
in British Columbia, and Seoul
National University. In 2014 we also
sent six students to join the KAIST
one month summer workshop
program. The following records
some impressions by the students
who were sent out in the summer of
2014. More details on the scheme
can be found at the following link

contained making it ideal as a
summer project. Living on campus
meant that I had a ten minute walk
to work every day and could buy a
coffee on my way in. I worked in a
room with other undergraduates and
a friend from imperial was a few
doors away from me making it a
very pleasant working environment.
The aim of the project was to
statistically analyse images from the
sky and try to determine the underlying
brightness distribution of the resulting
blurred image. The project involved
accessing a super computer using a
Linux based system and writing up
code in python. I had never used
Linux before and only learnt C++ in
Uni part of the challenge was to
learn the two new languages and
get used to them. The people I
worked with were very friendly and
helpful making this a very enjoyable
and valuable experience.
After that my job was to write up
code that could simulate the sky and
then apply a fitting algorithm on it to
see whether it would come up with
the original distribution. Unfortunately I
didn’t have time to apply my code to
We sent Kofi Mundy-Castle, Tim
Harrington, and Andrew Warwick to
Seoul National University. Here is a
short description from Tim:
Spending eight weeks in Seoul
National University, South Korea,
was a fantastic, once in a lifetime
experience. It gave me the opportunity
to live in a country surrounded by an
interesting culture, working alongside
accomplished physicists in an area
of research I was interested in. I
managed to meet lots of people in
order to live like a true Seoulite
while also travelling the country and
exploring the vibrant, dynamic
capital on weekends.
Thomas Whiting and Leon van
Riesen-Haupt travelled to Vancouver.
Here is part of Leon’s exchange
After a nine hour flight and a long taxi
ride to the student accommodation I
arrived in my room and realised this
would be my home for the next eight
weeks. My project was in the
Astrophysics group and was self-
strengthened and refined my
practical skills in handling technical
equipment, which is a fundamental
aspect of science that can
sometimes be overshadowed by the
mathematics and the formulae:
theory would be pure speculation if
there were no experimental devices
able to test it. I am now very
competent in using various kinds of
data analysis software, also
employed in several other fields of
science, which I will almost certainly
get to use again. The group held
two weekly meetings: these trained
me in summarising the progress that
had been made and explaining it to
an audience unfamiliar with the
specifics of my experiment, in order
for others to make suggestions on
how to tackle any problems. They
also allowed me to reflect upon other
people’s difficulties, whilst becoming
acquainted with what everyone was
working on. At the end of my stay, I
wrote a report detailing the research
I carried out and I gave a power
point presentation summarising the
main results obtained: these
enhanced my oral and written skills
in presenting scientific work to an
expert audience.
This is a short description from
During my placement I joined Prof.
Levitov’s group within the department of Condensed Matter Theory.
My research centred on a variety of
topics related to graphene. Every
problem required different set of
methods and techniques to be
employed, which although challenging
at first, was immensely educational.
The main project focused on
investigation of properties of a
circular p-n junction, which arises
due to the interplay of Fabry-Perot
resonances and quantum tunnelling
into the system from an STM tip.
Together with Prof. Levitov we
developed a model, which potentially,
in addition to providing qualitative
understanding, will also describe
experimental data quantitatively too.
Aside of the research project to
which I dedicated most of my time, I
really enjoyed the summer at MIT.
Together with fellow exchange
students we went on several
sightseeing excursions and I found a
little bit of time to enjoy Cambridge
and Boston as well, not to mention
the variety of wonderful running
routes alongside Charles river.
Overall I found the summer research
placement at MIT extremely useful
and given another chance I would
have applied for it again!
Malik, Yasmin, Jonas Evaeus, Jan
Piech, and Alexander Soloviev all
travelled to KAIST for the summer
Here is a short description from
Annyeonghaseyo! This summer I
was lucky enough to complete a 4
week research placement, along
with 5 other students from the
physics department, at the Korea
Advanced Institute of Science and
Technology (KAIST). The university
is situated in Daejeon- the country’s
fifth largest city, south of the capital
city Seoul.
I was assigned to the optics
laboratory, where I was given the
task of investigating the propagation
of ultrafast pulses in nonlinear and
dispersive optical fibers. The
finished product was a program I
wrote in C++, which simulated the
evolution of an initial pulse according
to user-defined parameters,
corresponding to the properties of
the fiber.
Aside from our placements, we
partook in numerous excursions and
cultural activities, ranging from all
terrain vehicle and rafting in Muju, to
ceramics painting in Icheon. We also
took trips to Seoul, where we visited
old and new attractions alike, for
example the Changdeokgung and
Gyeongbokgung palace as well as
the Namsan Tower. We were even
treated to a tour of Samsung
Electronics’ flagship showroom. I
thoroughly enjoyed my time in South
Korea, and I would like to thank the
international offices of both Imperial
College and KAIST as they were
extremely helpful over the course of
the trip. I would definitely
recommend doing an international
research placement to any students
that may be considering it for next

actual data, however, my supervisor
said he was still pleased about my
progress and that I should contact
him if I wanted to apply for a post
grad at UBC.
The exchange was also a wonderful
cultural experience. Living in
Vancouver for two months meant
that I got a proper experience of the
city and not just what a tourist would
see. UBC itself was on first nation
grounds and right next to the Pacific
spirit forest. It is situated at the end
of a peninsular west of downtown
Vancouver meaning that it was
almost completely surrounded by
coast. The ride into the city took less
than half an hour with the 24/7 bus
service so it was easy to go
sightseeing or just downtown with a
few friends. All this meant that
during the week there was always a
lot to discover after work. I also
rented a car and crossed the US
border twice; once to go camping in
the North Cascade national park
with a group of people I had met at
UBC and once to go to Seattle for a
week end with a group of other
Imperial students.
Rosanna Nichols, Cyprian
Lewandowski, and Matteo Sbroscia,
travelled to MIT. Matteo has
submitted the following description
of his visit.
The Massachusetts Institute of
Technology has been ranked 1st
university in the world this year
(2014): it has a history of
accomplishments that has
established its role in the
advancement of science and it
continues to stand out as one of the
most exciting centres of scientific
research in the world. As a
consequence, it attracts scientists
from all over the world who
represent the very best of their
countries’ academic excellence. I
had the privilege of working in an
international environment, with
nearly 10 different nationalities in
my group alone: discussion about
everyone’s habits and culture was a
very enriching experience, and one
which resulted in a friendly rivalry
during the Football World Cup
matches that we watched together.
Our hall of residence was also rich
in cultural diversity: there were 10
nationalities within our exchange
group, plus American students
enrolled at MIT with whom we
socialised and discussed.
The focus of my studies is mainly
theoretical, as I am pursuing a
degree in Theoretical Physics,
which is what motivated me to
undertake a summer internship in
experimental physics. It

2014 Activities
The department has a
dedicated Outreach office,
managed by a Senior
Teaching Fellow, Dr Mark
Richards and employing
full-time two other members
of staff (Hannah Woods
replaced part way through
by Vinita Hassard and Dr
Simon Foster). Funding in
support of these activities
has been awarded by the
Ogden Trust and the RCUK
School University
Partnership Initiative. Simon
Foster trains and supports
staff and students to
participate in outreach and
public engagement, as well
as undertaking his own
bespoke Outreach activities
associated with the three
EPSRC funded Centres for
Doctoral Training.
During 2014 the department undertook
numerous activities such as talks,
workshops, and interactive
demonstrations with schools, local
societies, teacher groups, and other
likeminded institutions (such as the
Institute of Physics). We have
attended HE fairs, science careers
events and national science events
(including the Expo Science Fair,
Cheltenham science festival, Big
Bang fair, Science Uncovered, and
the Royal Society Summer Exhibition).
In 2014 Physics staff members
presented many outreach and public
understanding talks. These activities
are listed at
Engaging Young People
Insights Work Experience
In 2014, the department ran its
flagship Insights work experience
scheme for the third year running.
The scheme is designed for year 12
students in schools with little or no
previous connection to the College,
thereby widening access. It offers an
opportunity for able students who
attend such schools to obtain a
glimpse into research as well as
experiencing the life of an
undergraduate. We received nearly
800 applications for the 2014
insights scheme, and recruited a
cohort of 40 students.
Open Days:
The Department Open Days
continue to be a great success;
around 20% of our final student
intake attended our open days.
They are aimed at showcasing
recent research, providing an insight
into physics courses, and examples
of careers that can result from a
physics degree. Throughout the
year, special emphasis may be
placed on attracting GCSE students
(years 10-11), A-Level physics
students (years 12-13), and girls
through the Juno annual Women In
Physics open day. In 2014, we
welcomed approximately 1500
students in the department .
Special Events:
Tutored sessions with the Amos

students studying both A-level
mathematics and physics the aim
was to show how the two subjects
are intertwined whilst also preparing
them for some of the more
challenging aspects on the syllabus.
This event was run twice in 2014.
Communicating Physics:
Undergraduate students can
nominate Communicating Physics,
as one of their accredited option
courses in either their second or
third year. Students are placed in a
London school for ½ day per week
over a period of 10 weeks. The
course is expanding year-on-year,

The Department of Physics at Imperial College is one of
the largest Physics departments in the UK. The
Department’s research covers a comprehensive range
of topics in theoretical and experimental fields and has a
flourishing postgraduate research and taught MSc
community. We offer seven Master’s level taught
postgraduate courses, as well as the extended Masters
in Physics as a two year full time course. Our first
students in this extended Masters graduated recently. A
new element in our one year MSc in Physics are two
streams dedicated to Shock Physics, and to
Three of our masters courses are associated with
EPSRC Centres for Doctoral Training (CDTs), the areas
of which are Controlled Quantum Dynamics, Plastic
Electronics and Theory and Simulation of Materials. The
CDT courses can lead directly to PhD studies and were
successfully renewed this year.
PhD research fields extend from astronomy, space and
plasma physics to high energy, theoretical and atomic
physics, and condensed matter theory. Solid state
physics, plastic electronics, laser physics, applied optics
and photonics, nanophotonics/plasmonics and
metamaterials as well as quantum information are all
areas where there are close collaborations with industry,
as well as providing opportunities to study fundamental
underlying principles. The Department has had a
successful year in attracting the best students
worldwide via the Imperial College PhD Scholarship
scheme (six students funded) and the joint Imperial /
National University of Singapore (NUS) PhD
programme, where two students have joint.
There are many examples of international and industrial
collaboration involving our research groups and we are
also very strongly involved in interdisciplinary research
centres around the College. We are directly linked to the
Thomas Young Centre (TYC), the Shock Institute, the
Centre for Plastic Electronics (CPE), the Institute of
Chemical Biology, the Centre for Plasmonics and
Metamaterials and the Grantham Institute for Climate
change – all of which are centres of interdisciplinary
research within the Imperial College campus. Many
groups are involved in research using large scale
facilities. The Department has extensive internal
facilities and a tremendous range of research topics
available to postgraduate research students.

Rebecca Lane
Group: HEPP
Supervisor: Dr D Colling
Rebecca’s Ph.D research focussed
on analysing proton-proton collision
data from the world’s largest particle
accelerator: the Large Hadron
Collider (LHC). The data was taken
by the Compact Muon Solenoid
(CMS) detector throughout the years
of 2011 and 2012 and analysed in
different ways to probe the
properties of the Higgs boson
discovered at the LHC. The Higgs
boson is observed via the final
states it decays into, and Rebecca’s
work was to study the final state of
two tau leptons. Only by observing
the Higgs boson in all of its predicted
decays and making precision
measurements of their relative
decay rates can we ensure that this
discovered particle is the Higgs
boson predicted by the Standard
Model of Particle Physics.
During Rebecca’s Ph.D, she spent
two years based at CERN near
Geneva. She worked as part of a
group of researchers from many
institutes across the world to develop
an analysis to study the Higgs in the
final state of two taus in the context
of the Standard Model, while also
developing interpretations of the
data in other possible new-physics
models. She participated in two
papers incorporating the data taken
during run 1 of the LHC - one of
which documents the first evidence
of the Higgs in the final state of the
two taus with consistency with the
Standard Model, and the other
which interprets the data in the
context of the Minimally
Supersymmetric Standard Model - a
popular beyond the Standard Model
theory which is a subset of
Supersymmetry and has not so far
been discovered. Recently Rebecca
gave a talk at the internationally
renowned Moriond QCD and High
Energy Interactions conference in La
Thuile, Italy, summarising the latest
results in Higgs decays in all
fermionic final states.

Ben Dive's project looked at the
ability to manipulate quantum
systems in the presence of a noisy
environment. He specifically looked
in ways in which the dynamics of a
qubit and its environment can be
replicated by one which is well
controlled and isolated from its
environment. He showed that in
some cases the addition of classical
probability was sufficient to do this,
and presented a poster on this at the
QUICC summer school in Exeter. In
addition, he came up with a way to
solve the problem in a general case
using only a small ancilla space and
well behaved Hamiltonians. The
project was done jointly with
Aberystwyth University, so he had
the pleasant experience of spending
half of summer working by the sea in
Wales. His current PhD is expanding
upon the work he did over summer,
and he is preparing some of the
results for publication.
Oliver Pike has been a PhD student
in the Plasma Physics Group at
Imperial College for the last three
years, funded by an EPSRC
studentship with a CASE top-up
award from AWE Aldermaston. His
work focuses on theoretical aspects
of high energy density plasma
physics and he has published
several first author papers in the
area of relativistic effects in
plasmas. One of his most notable
pieces of work explained how it may
now be possible to use ultra-highpower lasers to study fundamental
quantum physics in the laboratory.
Oliver was the lead author on a
recent Nature Photonics paper that
showed theoretically how the elusive
Breit-Wheeler two-photon pairproduction process could be studied
in the laboratory, some 80 years
after it was first proposed.
This process is the "simplest" method
by which light can be transformed
into matter, but has proven
remarkably difficult to demonstrate
experimentally due to the very
extreme conditions required. The
paper received an astonishing
amount of publicity in the scientific
and popular press. Oliver has since
been working closely with AWE on
practical designs for an experiment
that can be undertaken on their
large ORION laser facility, hopefully
in 2015.

Nuclear power is a reliable and clean
source of energy that offers low CO2
emissions. As the industry progresses,
it is crucial that nuclear reactor
technology continues to become
safer. During the MSc I modelled a
diffusion mechanism that is responsible
for the embrittlement of nuclear fuel
cladding. This involved the classical
field theory of the interaction between
the diffusing species and continuum
fracture using Green tensors and
singular integral equations. In my
current PhD research, I am using
conformal mapping to describe the
concentration profiles ahead of elliptical
voids in the component. This work
builds on another PhD project in which
many-body quantum mechanical
simulations were used to identify the
role of the diffusing species within the
cladding material. I work at the boundary
between condensed matter physics
and engineering, interfacing theoretical
and computational methods; I am
supervised by Daniel Balint (Mechanics
of Materials, Mechanical Engineering),
Mark Wenman (Centre for Nuclear
Engineering) and Adrian Sutton
(Condensed Matter Theory, Physics).
We are applying fundamental physics
to a problem of major industrial
importance and we work in close
collaboration with Rolls-Royce.

– Controlled Quantum Dynamics CDT
Joe's research has centred on the
development of experimental techniques
for the cooling and manipulation of
calcium ions in a Penning ion trap. In
particular, he provided the first
demonstration of resolved-sideband
laser cooling in a Penning trap,
allowing the ions to be cooled to their
motional quantum ground state. This
important result opens the door to a
wide range of new techniques that
have previously been limited to radiofrequency ion traps. Coupled with the
intrinsically low heating rate of the
Penning trap this will provide an
environment of unparalleled isolation in
which to study a range of sensitive
phenomena in quantum thermodynamics and quantum information.
Joe has also conducted theoretical
research into novel schemes for
generating many-qubit entanglement
in ion Coulomb crystal lattices. Of
special interest is the application to
small error-correctable quantum
memories in a Penning trap, where
symmetries of the crystal can be
exploited to greatly reduce the
complexity of the protocols necessary
to produce the entangled state.
The results of his work have been
published in two papers in leading
international journals, with a further
two papers currently in peer review.
He has recently been awarded an
EPSRC Doctoral Prize Fellowship
and is currently a research associate
in the Quantum Optics and Laser
Science group at Imperial College."
Michel Buck
Supervisor: Prof F Dowker
Group: THEO
Michel Buck's thesis was in the area of
the causal set approach to quantum
gravity. The focus was investigating
a privileged state, the SorkinJohnston (SJ) state, for scalar
quantum field theory derived from
the causal structure of spacetime.
In a causal diamond in 2 dimensional
flat space, he found that for the
massless scalar field the SJ state
approximates the state between two
perfect mirrors positioned at the
spacelike corners of the diamond. In
deSitter spacetime, which is of great
interest to cosmologists both because
of inflation and the acceleration of
the expansion of the universe today,
the SJ state depends on the
spacetime dimension, mass of the
field, and on the choice of subregion,
differring in many cases from the
usual Bunch-Davies vacuum. This
may have implications for early
universe cosmology, indicating a
physical role for certain deSitter
invariant “alpha” states.
Michel published 4 papers before
graduating and in November 2014
he took up a postdoctoral research
position in the Department of
Physics at Northeastern University,
Boston MA, USA.

The Astrophysics group studies the Sun, the birth of stars in the Milky Way, the formation and evolution of
galaxies over cosmic time, the cosmic microwave background, and the nature of dark matter. The sophisticated
use of statistics in interpreting astronomical data is a common theme in the group’s activities.
Unruh, Mohanty,
The radiation of the parent star and
its variability is crucial to the
habitability of exoplanets.
Unruh works on solar and stellar
magnetic activity and the its effect
on the radiation emitted by the star.
This is relevant to the influence of
the Sun on climate change on the
Earth, and to the habitability of
extrasolar planets.
Thousands of planets have been
discovered around other stars in
recent years, and it now seems
likely that every star has one or
more planets around it. Mohanty's
research focuses on understanding
how these planets are formed out of
the disks of gas and dust surrounding
newborn stars; how this process is
linked to the formation of the stars
themselves; and how stellar properties
influence the characteristics - in
particular, the habitability - of the
orbiting planets.

the evolution of the universe we see

these questions, using telescopes
such as UKIRT, Herschel, JCMT, the
SMA, and ALMA, with an emphasis
on the highest redshifts observable,
z>6. Pritchard is leading activities to
predict the 21cm radio signature of
neutral hydrogen from the first billion
years to study the nature and evolution
of the first stars and galaxies.

Trotta, Scott
Decades of studies have led to the
conclusion that 80% of the matter in
the Universe is made of a new type
of particle, and the experimental
hunt for this dark matter is now in a
crucial phase. The question of the
nature of dark matter is one of the
most important in all physics.
Our work aims to put constraints on
the physical parameters of
theoretical models for dark matter
(such as Supersymmetry) by
combining four complementary
probes: cosmology, direct detection,
indirect detection and colliders. Our
group has developed the worldleading “global fits” approach to the
problem, allowing us to explore in a
statistically convergent way
theoretical parameter spaces
previously inaccessible to detailed
numerical study.

The incredible success of the Herschel
mission, and especially its deep,
cosmological surveys, has continued
to shed light on the role that dusty
galaxies play in the formation of large
scale structure and the history of
galaxy formation. Multiwavelength
followup observation campaigns are
underway to determine the nature of
the reddest, and thus potentially most
distant, objects seen in these surveys.
The first fruit of this work was the
discovery of HFLS3, a massive, rapidly
star forming dusty galaxy at the
unprecedented redshift of 6.34.
Finding such an object just 880
million years after the Big Bang is
wholly unexpected in current
cosmological models. As well as
seeking individual high redshift sources,
we have been cross-matching
Herschel and Planck data to look for
groups or clusters of star forming
galaxies at somewhat lower redshifts.
The first results of this work have
uncovered four candidate galaxy
clusters whose constituent galaxies
are forming stars at a very high rate,
and which lie at significantly higher
redshifts than conventional optical/IR
or X-ray observation can easily detect
clusters. We appear to be detecting
these objects during a formative but
otherwise inaccessible phase in their
formation and evolution.

The first Planck cosmology results
were published in 2014, showing
that primordial non-gaussianity in
the map is constrained to be very
close to zero, in agreement with the
standard inflation model for the early
Universe. The robustness of the
result was shown using a statistical
technique partly developed and
applied by us.
A key observable in cosmology is
the sound horizon (the ‘BAO’ scale),
which leaves an imprint in the
clustering of galaxies. We have
determined the length of this
standard ruler, for the first time in a
model-independent way, not even
assuming General Relativity. The
Universe still looks like the standard
LCDM model and the number of
neutrino species is constrained
almost model-independently to be
3.5 ± 0.3. Published in PRL.
We applied our method of 3D weak
lensing analysis to the leading
survey (CFHTLenS). Results show
for the first time hints of baryon
feedback or suppression of power
on small scales due to non-zero
neutrino masses.

Our work has concentrated on the
analysis and interpretation of data
from the cosmic microwave
background (CMB). In particular, we
have a team (Jaffe along with
PDRAs Ducout and Feeney)
dedicated to working with data from
the Planck Satellite which has
released two rounds of cosmological
results and is poised for completion
in 2016. We have been involved in
all aspects of the analysis, from
detailed examination of the optical
properties of the instrument to the
use of Planck data to limit the largescale topology of the Universe on
scales of billions of parsecs. We
also apply this expertise to groundand balloon-based CMB
experiments such as EBEX and
PolarBear. The latter was the first to
directly detect anisotropy in the
polarization of the CMB from
gravitational lensing of structures
along the line of sight; this will prove
a strong test of instrumental
properties, astrophysical sources of
microwave emission, and,
eventually, of cosmological
parameters that will inform us about
the possibilities of an early epoch of
cosmic inflation responsible for both

Ground and space-based missions
have uncovered thousands of
exoplanets around other stars in the
last few years. My work focusses on
how these planets form out of the
primordial disks of gas and dust
around young stars, and how the
properties of the host star influence
planetary characteristics (particularly
habitability). Highlights over the last
year include determining average
disk masses (which ultimate set the
planetary masses), from dust
emission, for a broad range of stellar
types (reference [1]), and building a
theory of how magnetohydrodynamical
processes affect the disk structure
and evolution (reference [2]).
Ongoing work includes devising a
semi-analytic model for forming
super-Earth size planets very close
to the host star (which empirically
seems to be the dominant mode of
planet formation), and constructing a
model of X-ray and UV-driven
photoevaporation of terrestrial
planetary atmospheres within the

The main theme of my research has
been to increase our understanding
of conditions in the first billion years
after the Big Bang during which the
first generations of stars ionised the
hydrogen in the Universe. The main
route to doing this has been to
analyse follow-up observations [1,2,]
of the quasar ULAS J1120+0641,
the most distant known to date and
hence the earliest bright
astronomical source available for
study [3]. I have been involved in
theoretical efforts to understand the
population of quasars in the early
Universe and in interpreting the
signatures of the cosmological
ionisation process as revealed in
their spectra. I have also applied
Bayesian inference techniques to
several areas of astrophysics in

old science case. I have played a
leading role in both aspects of this –

meetings at SKA-HQ in Manchester
to review the baseline design and, in
my role as co-chair of the Epoch of
Reionization SWG, leading the

rewrite of epoch of reionization/
cosmic dawn sections of the SKA
science case and co-writing four
chapters. This connects to my new
role as a member of the UK-SKA
science committee to promote
involvement in SKA science within
the UK. Alongside this, with my
student Catherine Watkinson, I have
completed two papers demonstrating
the importance of 1-point statistics
of the 21cm signal for determining
the reionization topology and the
impact of small absorbing systems.
Finally, I completed part of a review
on atomic physics in the early
universe covering topics from the
CMB & recombination to the 21cm
signal and reionization.

Solar and stellar surface magnetic
fields and their evolution are the
cause of much of solar and stellar
variability on time scales of a few
hours to months and even decades.
The emergent magnetic surface flux
forms dark spots as well as bright
points that contribute to the
changing solar and stellar emission.
The wavelength dependence of their
emission is still an outstanding
question, though much progress has
been made in the case of the Sun
where we are now able to model the
wavelength dependent irradiance
changes to a high degree of
accuracy which is needed for
modelling the Earth's (upper)
atmospheric response (e.g., Ball et
al, 2014).
Comparable stellar variability is
usually considered as `noise' and
presents a nuisance in the detection
and characterisation of exoplanets.
The importance of including stellar
variability in the exoplanet modelling
so as to minimise spurious
detections and allow the
characterisation of exoplanets
around more variable stars was

have been particularly interested in
using a new wide-area deep survey
at near-infrared wavelengths (0.92.3micron) to find brown dwarfs and
distant quasars. Brown dwarfs are
collapsed clouds of gas where the
mass is too low for the central
temperature to get high enough to
ignite hydrogen. These are some of
the closest objects to Earth. Nathalie

Materials have played a central role
in the development of civilisation
from the Bronze Age to the Semiconductor Age.
We aim to understand and predict
the properties of materials and the
processes by which they grow or
transform. We also provide guidance for experimental research,
help to interpret observations, and
seek ways to enhance materials’
properties. Our theoretical work is
often helped by simulations, which
include accurate quantum mechanical calculations, atomistic and more

Specific systems of interest include
dissipationless phases of matter,
which may be useful for quantum

Our work continually throws up fundamental questions relating to quantum mechanics and how thermodynamics may be adapted to

Metamaterials are artificial solids
designed to guide electromagnetic
fields or acoustic waves. The properties of conventional materials are
determined by chemical composition
and how the atoms are arranged.
Metamaterials, on the other hand,
consist of arrays of specially-engineered units organised on much
larger length scales. They can be
designed to manipulate photons and
electrons in ways that cannot be
achieved with conventional materials. This has inspired scientists to
conceive perfect lenses, new lasers,
'invisibility cloaks’ and opened the
door to slow and stopped broadband light.
Metamaterials are lattices of metamolecules, such as “split-ring resonators” (left). A layered
metamaterial can slow a light packet while spatially separating its colours to make a “trapped
rainbow” (right).

Universal relationships between city
size and pace of life have inspired a
unified theory of urban living but
individual variation within societies
poses a challenge for planning and
prediction. Controlled experiments
are essential. We demonstrate a
universal relationship in ant
societies: average ant speed is
higher for longer activity events.
This suggest that activity duration is
already specified when the ant
begins to move and this approach
may inform the engineering and
control of artificial social systems.
We are convinced that our main
conclusion that the duration of an
activity event is determined before it
commences is likely to be applicable
as a general principle of animal
behaviour across taxa including
humans. Complex data series that
arise during interaction between
humans and advanced technology
in a controlled and realistic setting
have been explored. The purpose is
to obtain quantitative measures that
reflect quality in task performance:
on a ship simulator, nine crews have
solved the same exercise, and
detailed maneuvering histories have
been logged. Quantitative measures
of task performance have been
constructed and the crews differ
significantly under these objective
measures. Our approach may be
useful for other qualitative concepts
of biased Monte Carlo `flat
histogram’ methods, which
addresses the problem of
calculating the configurational free
energy of oxides bearing a high
concentration of charged point
defects. Ongoing research is aimed
at understanding the growth
mechanism of oxide films and how it
can be controlled (ref.4) . A new
insight from this work is the need to
understand grain boundary electrical
conductivity, since it is of the same
importance for the growth rate as
ionic conductivity.

Compressed hydrogen gas solidifies
at high pressure to form a crystal of
H2 molecules. As the pressure is
increased the crystal undergoes
several phase transitions, but
hydrogen atoms scatter X-rays so
weakly that the structures of the
Department of Physics Review 2013 -14
new phases are unknown.
Eventually, at high enough pressure,
hydrogen is thought to become not
only a metallic atomic solid
(believed present in large quantities
in the interiors of Saturn and Jupiter)
but also a high-temperature
superconductor. Investigating the
phase diagram of solid hydrogen
was the focus of much of our work
this year. We started by using
density functional theory to calculate
the low-temperature phase diagram
[1], but concluded that the results
were too inaccurate to be useful.
This led us to combine quantum
Monte Carlo simulations with a fully
anharmonic study of zero-point
fluctuations [2]. Attempts to create
metallic H on Earth have not yet
succeeded for sure, but our highly
accurate results support recent
experimental hints that success is
close. Other work has included the
development (with undergraduates
Nick Blunt and Tom Rogers) of a
new finite-temperature quantum
Monte Carlo method [3] and a

Superfluid helium has long been a

Bose-Einstein condensation and
superfluidity. Nevertheless, it
continues to come up with surprises
that challenge our understanding.
Recent experiments [1] on thin
helium films on graphite appear
contradict all textbook descriptions.
Since this is found near the
solidification of the film, a tantalising
candidate for this new phase of
matter is the elusive supersolid –dissipationless mass flow in a
crystal, originally proposed for bulk
helium but recently refuted by new
In a theoretical collaboration

The strange behaviour may be
connected to the fact that the
system is close to a quantum phase
transition to a solid. Quantum
criticality is an important area of
research in condensed matter
physics. Indeed, the rich physics
behind the cuprate superconductors
may be tied to its proximity to a
quantum transition to a magnetic
insulator. This helium system is

Metal surfaces support electron
density waves known as surface
plasmons which can couple to
externally incident light waves.
Since the surface plasmons have
wavelengths of the order of a few
tens of nanometres or less, they can
be focussed into extremely small
areas. This extreme concentration
has the potential for single molecule
sensing, enhanced optical non
linearity at low power input and
many other applications where an

intense concentration of optical
energy is needed. Surface plasmon
properties are extremely sensitive to
surface structure, particularly to
singular features such as two
touching curved surfaces. We use
the technique of transformation
optics, developed here in London, to
explore relationships between
geometrically distinct structures, but
which can be mapped into one
another by coordinate transformations
that preserve all the spectral
properties. Apparently complex
systems can be related to simpler
ones and their spectra solved
analytically. Furthermore it has often
proved to be the case that the
simpler system is highly symmetric
enabling the spectrum to be classified
by the symmetry representations.
We call this ‘hidden symmetry’ and it
has given powerful insight into
systems which previously were
thought to be just a complex
mathematical mess

One example is alumina, where we
have studied defect structures and
diffusion mechanisms with a view to
better understanding the growth of
oxide layers on superalloys [2] .
Force fields can generate realistic
structures and the electronic
properties of these structures can
then be calculated with DFT.
We are also interested in the

multiferroic perovskites, the simplest
of which are BaTiO3 and SrTiO3.
With force fields we can reach a

we can go further by using
advanced statistical techniques to
elucidate the complex process by
which ferroelectric domains
nucleate, grow, and coalesce.

the acids in DNA). Clinical trials are

Here we utilise metallic nanostructures in to break the diffraction limit of
light. Examples include ultrafast
plasmon lasers, highly sensitive
biodetectors, quantum plasmonics
and optical nanoantennas for use in
nonlinear nanooptics.
Nanophotonic structures are also
fascinating materials for combination
with graphene for novel optoelectronic
devices. At mid-infrared frequencies,
we have developed the concept of
quantum metamaterials based on
highly doped semiconductors for
novel sub-resolution imaging applications.

My research programs are centered
on understanding the physical
properties of functional electronic
materials and applying this
fundamental understanding to
develop improved materials and
devices for application in
electronics, displays, lighting,
energy generation & harvesting and
different sensor technologies. I am
also interested in innovative
manufacturing technologies for
large-area nano-electronics where
device –and ultimately system–
performance is determined by key
device dimensions rather than
strictly by the physical properties of
the active material(s) used. Ultimate
aim is the development of advanced
device concepts and their
application in future generations of
ubiquitous large-area optoelectronics. Current research
interests falls into three broad

novel fabrication paradigms

processed semiconductors offer the
prospect of cheap solar power, but the
stability of the materials is often
limited. We have accelerated aging in
photovoltaic devices based on low
processing cost materials such as
CH3NH3PbI3 perovskites,
conjugated polymers, and dye
sensitised solar cells (DSSCs) by
using high intensity light sources to
expose devices to the equivalent of
a year’s flux of photons on the time
scale of a few days.[1] Our approach
enables us to assess the extent of
photo-degradation and mechanisms
for change in behaviour in these the
materials. DCCS proved to be the
most stable but can suffer from
electrolyte sealing issues. To overcome
this we are exploring routes to improve
the performance of solid-state DSSCs
using lateral transport of holes through
dye monolayers attached to surfaces.
This ‘molecular wiring’ phenomenon
also has potential applications in
batteries, solar fuel photoelectrodes,
and molecular scale electronic devices.
We have developed a new method to
experimentally measure the
reorganisation energy of charge
hopping in these molecular monolayers
which shows excellent agreement
with our theoretical calculations.[2]
This allows us to predict the mobility
of holes for different molecules and
environments, suggesting interesting
new possibilities for the design of
organic electronic devices.[3]

create organic light emitting diodes

and organic phototransistors which
emit and detect circularly-polarised

application in protein detection, CP

spintronics and quantum computing,
and displays, and a patent from this
work has led to further funding and
an industrial collaboration [3]. We
also have strong activity in the
POLARIC (printed organic largearea realisation of integrated

involved printing high performance

complementary circuits. As well as
ultra-thin contact printed dielectric

One of the first ever demonstrations
of a hot carrier photovoltaic device
was demonstrated in the group,
showing a hot carrier photocurrent
at a device cooled to 10K. Research
is on-going in collaboration with Sharp
Laboratories Oxford to demonstrate
a hot carrier photovoltaic device at
higher working temperature and with
a broader absorption profile. A new
milestone for multi-junction solar cell
development was passed in a
collaborative project with the
University of Tokyo where a 1.15eV
band-edge using aggressively
strain-balanced GaAsP/InGaAs
quantum well was demonstrated.
Further research has shown that
radiative transport within a 4J
structure will lead to efficiencies in
excess of 50%. Further, we have
discovered remarkable microsecond
minority carrier lifetimes present in
lateral GaAsP/InGaAs quantum wire
solar cells in collaboration with the
Fraunhofer Institute for Solar Energy
Systems in Freiburg. Our research

gigantic enhancement of higher

the physics, chemistry, materials
science and device engineering of
new, solution processible materials
for solar cells. These include organic
semiconductors such as conjugated

hybrid inorganic:organic materials
and dye sensitised and perovskite
materials. We study the factors
controlling current generation and
charge recombination in organic and
hybrid solar cells, such as the role of
trap states, doping and interface
recombination using detailed analysis
to determine the practical and
theoretical limits to device performance.
We use a wide range of characterisation
techniques to study how the chemical
and physical structure of materials
control the processes of light
absorption, charge generation and
charge transport, and how these
processes influence photovoltaic
device performance. We are particularly
interested in charge transport and
photo-induced charge separation.
We have also developed methods to
simulate the physical structure of
materials, and the resulting electronic
and optoelectronic properties. Our
long term aim is the rational design of
functional electronic materials.
Together with the Grantham Institute
for Climate Change, we also research
the potential of new PV (and other)
materials technologies to contribute
to carbon emissions reductions.

My research involves engineering
the interaction of light and matter.
The stark difference in characteristic
length scales of photons and
electrons makes optical interactions
extremely weak despite light being
our primary means of experiencing
the world around us. However, the
characteristic wavelength light can
be matched with that of electrons in
materials with metal optics. Metal
surfaces support excitations, called
surface plasmons, that can be
squeezed into spaces just tens of
nanometres in size where lightmatter interaction are greatly
accelerated. While this technique
can be used to make brighter and
more efficient light sources, Dr.
Oulton is currently using this
concept to create ultrafast lasers
capable of turning on and off within
a few hundred femtoseconds1. The
approach also strengthens the
weakest non-linear optics effects.
Metal-optics, or plasmonics, allows
light focussing down to the
nanometre scale2, far beyond the
diffraction limit of conventional
optics. This boosts light’s intensity to
enhance non-linear response. The
concept is also used in reverse:
artificial material states are created

absorption that lies at the heart of
the idea1.
In a similar vein, we make quantum
metamaterial “superlenses”, using
quantum theory to design structures
where light beams propagate
without spreading by diffraction2. To
test them we have developed a new
s-SNOM microscope, capable of
mapping IR spectra at a resolution
of 100th of a wavelength, and we
are using it to measure chemical
distributions within single cells for
the first time3.
Our “Digistain” IR imaging method
for earlier cancer detection is
undergoing clinical trials in Charing

Southampton and Bath promises a
new form of coherent radiation
emitter, that uses a quantum-optical
effect known as “Rabi flopping” in an
asymmetric nanostructure, to
generate tunable THz beams.

High Energy Physics
The High Energy Physics Group has activity across a broad front in exploiting particle physics experiments at existing facilities
as well as designing detectors and accelerators for future experiments. These investigate the fundamental particles
and the forces between them, with a primary aim to address basic questions such as the origin of mass and the
charge-parity (CP) asymmetry between matter and antimatter. The group have also been exploring possible
applications of accelerator technology in healthcare, working jointly with the Imperial College Medical Faculty.

We have been heavily involved in the
CMS detector at the LHC and in the
discovery of the Higgs since inception.
The trigger (a real-time background
rejection) and the entire tracking detector and forward calorimeters will be
replaced within the next decade. We
develop custom readout electronics for
the new tracker and trigger and we lead
the design of a novel high granularity
neutrino disappearance.
SuperNEMO searches for neutrinoless
double-beta decay, a process that
allows access the fundamental nature
of the neutrino mass. We lead the software development. Intense beams of
muons at high energy can give neutrino
beams with a well known composition
and energy spectrum – the so called
Neutrino Factory (NF). We lead the
MICE experiment to provide the proof
of principle for the technique.
Many models for new physics predict
lepton flavour violation, such as muon to
electron conversion. COMET/PRISM will
be sensitive to this process, with
COMET Phase-I currently under construction as a flagship experiment at
the J-PARC laboratory alongside T2K.

The LHCb detector at the LHC is optimised for measuring b-quark hadrons.
Imperial's main contributions to the
detector were the Ring Imaging

programme possible. We lead the
search for CP violation and new
physics. We have also continued to
jointly lead Higgs studies at DZero at
the Tevatron, culminating in further evidence for a 125GeV Higgs boson in
fermion decays, along with a measurement of its spin state.

Direct Dark Matter Searches
H. Araujo, T. J. Sumner
We are heavily involved in direct
searches for the dark matter particles,
which are thought to account for most
of the mass in the Universe. Currently,
the LUX experiment at the Sanford Lab
in the US places the most stringent
limits on the interaction of these particles with ordinary matter. In
The LUX-ZEPLIN detector
parallel with this, we lead the UK programme towards the next-generation
experiment, LUX-ZEPLIN, which is
entering its construction phase.
Gravitational Wave Detection
H. Araujo, T. J. Sumner
We have recently seen two major milestones in the LISA low-frequency gravitational wave ‘telescope’ in space. We
have delivered flight hardware for the

source, and LHC upgrades. The activities include the development of a compact proton accelerator based on
laser-plasma technology and the
design of innovative beam gantries
using FFAG technology.

teams. A reanalysis to enhance our
sensitivity to even lower particle
masses is near publication, led by
Alastair Currie from Imperial. A yearlong run is now underway which
should see LUX extend its reach
into unexplored parameter space. In
parallel, the LUX-ZEPLIN (LZ) nextgeneration experiment, presently
completing the conceptual design
phase, was selected by the US
funding agencies to become a
construction project from 2015. LZ
counts some 30 institutes mostly in
the US and in the UK (the UK
contribution is led by Imperial). We
are continuing our LZ-related R&D
programme here: our team is
investigating the phenomenology of
high-field breakdown processes in
liquid xenon, studying in particular
the emission of photons and
electrons from thin wires at several
hundred kV/cm. Another strand of
our work involves radiation detection
high above the Earth, rather than
underground. We are developing the
Highly Miniaturised Radiation

My major research project is the
CMS experiment at the LHC.
Following the discovery of the Higgs
Boson by the CMS and ATLAS
collaborations in 2012, the main aim
of our work has been to characterise
the newly discovered particle as
precisely as possible. In particular,
we need to check if the production
rates (in several production modes)
and the decay rates (in several decay
channels) are consistent with the
theoretical predictions. I have
concentrated on one particular decay
mode, which is Higgs to two
photons. This was one of the two
main channels contributing to the
discovery, mainly because it can be
reconstructed efficiently and so gives
high statistical power. As part of this,
we produced a paper describing a
new statistical method to allow for
background uncertainties. A final
paper on H→γγ decays using all the
CMS data from the 2012/13 LHC
runs was recently produced and so
far, all measurements are consistent
with the theory. However, the LHC
will turn on again in 2015 and run for
three years at a higher centre-of-mass
energy, increasing the Higgs data
sample by an order of magnitude
and allowing improved precision.
1. Handling uncertainties in background
shapes: the discrete profiling method, P. D.
My research has continued to focus
on characterisation of the recently
observed Higgs boson, both with
the CMS experiment at the LHC
and the D0 experiment at the
Tevatron, as well as searching for
non-standard model Higgs boson at
CMS. We published the legacy
paper in the Higgs to diphoton
decay mode, one of the principal
discovery channels, achieving
single channel evidence. The
combination of results from the
various decay modes continues to
yield results for the couplings and
spin in agreement with expectations
for the SM Higgs boson. Our
searches for invisible decay modes
constrain new physics theories,
including dark matter models.
Returning to this topic has been the
other thread in my recent research,
and I was very pleased to welcome
a JRF, Bjoern Penning, in this area.

2. Constraints on models for the Higgs
As Professor Emeritus I now use
my time to take an overall view of
the state of particle physics and
explore new directions which I feel
can be positive for the group. The
recent observation of the Higgs
boson at the LHC completes the
standard model and although this
explains almost all particle
interactions there remain areas
such as neutrino oscillation, gravity,
the matter-antimatter asymmetry
and dark matter still to be
understood. Thus our experiments
must now search for signals from
the physics beyond the standard
model. New avenues must be
explored in addition to the ongoing
LHC programme which has yet to
uncover any evidence.. Neutrino
oscillation is one observation not
predicted by the standard model
and hence the lepton sector is a
prime area to search for new
physics and the great prize would
be to see charged lepton violation

such as a muon changing to an
electron. I therefore now support
the COMET experiment at the
JPARC laboratory in Japan to
search for mu to e conversion.
Additionally more accurate
experiments are necessary in the
neutrino area and for this a neutrino
factory, long supported in this
group, remains the optimal

quark. A precision measurement is
important for measuring the least
well constrained free parameter of
the Standard Model. The present
measurements suffer from systematic uncertainties that can be
reduced by an analysis of the decay
Λb→pµν, something that can only
be done with the data from the
LHCb experiment. Further developments have been made in particle
physics phenomenology to improve
the interpretation of future experimental measurements.

The exploitation of the very large

involvement. Effort has concentrated on looking for signatures that
can constrain the nature of dark
matter or explain the prevalence of
matter over antimatter in the Universe. This means a continuation of
the analysis of B meson decays
where new types of particles are
created within virtual loops. The discovery of a resonant structure in the
dimuon mass spectra of the
B+→K+μ+μ− decay led to subsequent big developments for the
theory required to determine the
influence of possible particles not
described within the Standard
Model. A new direction of research
is related to semileptonic decays of

candidate for dark matter and the
baryon dominated Universe, require
further dedicated experiments.
Together with my colleagues I have
recently proposed a new experiment, SHIP, which will be based at
CERN’s Super Proton Synchrotron.
The experiment will search for heavy
Majorana neutrinos and any other
new particles that could be messengers between the Standard Model
particles and some “Hidden Sector”
of new physics. In particular, the
existence of Majorana neutrinos is
strongly motivated by both theory
and experimental evidence, as such
particles can simultaneously explain
the matter-antimatter asymmetry of
the Universe and account for the
non-zero neutrino masses. I have
been elected spokesperson of SHIP
and represent the 35 collaborating
institutes. CERN has asked our collaboration to produce an engineering design by the spring.
The LHCb experiment has recently
started a dedicated programme on
the exploration of hidden portals of
the Standard Model. Analyses of
large, and nearly background free data
samples of B decays to the final states
with muons have lead to strong
constraints on the couplings of the
Majorana neutrino and low energy

many activities on the experiment,
including supervision of the UK
detector operational responsibilities,
especially on the Tracker which
involved much Imperial effort and
hardware, and other managerial
activities. CMS is preparing an
upgrade and much of my time is
spent on that, where our group is
currently replacing the Level-1
calorimeter trigger and engaged in
R&D for new tracker detector
modules based on silicon microstrips
and a specialised front-end
electronic integrated circuit. This
module will provide new functions by
selecting data to permit reconstruction
of many of the charged particle
tracks emerging from p-p collisions,
and allowing this information to be
used in the L1 trigger for the first
time. This will increase the power of
the trigger, allowing CMS to be
more selective in data which are
preserved for full analysis, by
selecting high transverse momentum
tracks and associating them with
calorimeter and muon system
information. A prototype module of
this type was demonstrated in a
DESY test beam last December for
the first time. We have also carried
out experiments on silicon crystal
channeling in CERN proton beams.

Muon accelerators have been
proposed as intense neutrino
sources and as a means to deliver
Department of Physics Review 2013 -14
multi-TeV lepton-antilepton
collisions. What makes the muon
ideal for these applications is its
mass, 200 times that of the
electron, and the fact that its decays
are precisely calculable. We have
played seminal and leading roles in
the international and European
design studies that have established
the feasibility of such facilities.
Within these studies we have
contributed designs for the proton
source, the muon acceleration
systems and the muon storage ring.
The muon beam is produced from
the decay in flight of pions, which
means that it occupies a large
volume of phase space. Before the
muons can be accelerated it is
necessary to reduce the phase-space
volume that the beam occupies, a
process referred to as cooling. The
muon lifetime is so short that a
novel technique, ionization cooling,
is required to compress the phase
space. We have taken the lead in
the execution of the international
Muon Ionization Cooling Experiment
by which we hope to prove the
principle of the ionization cooling
thereby establishing high-intensity,
cold muon beams as a new
technique for particle physics.

My research is primarily focused on
the LHCb experiment at CERN's
Large Hadron Collider. I am
particularly interested in the use of
rare decay modes as probes for
physics beyond the current
"Standard Model" of particle
My recent papers include the first
measurements of the rare decay
B0s→μ+μ− that has been sought
for more than 30 years. The
measurements constrain the
properties of any new scalar
particles and have implications for
many new physics models. My
measurements of B0→K∗0μ+μ−
show some tension with the
Standard Model that may indicate the
existence of a new vector particle.
Further measurements of this and
related decays should help clarify
the situation. Similarly, my
measurements of B+→K+ℓ+ℓ−
decays, where ℓ=e, μ, show
electrons and muons, which behave
identically in the Standard Model,
have different decay rates. This has
stimulated interest in a whole raft of
similar measurements. Finally, I
have also made new asymmetry
measurements to probe anomalous
results obtained at other experiments.
I am also a member of the SHiP
collaboration. We are proposing a
new and uniquely sensitive
experiment at CERN to search for
new light particles that could help

Within the area of neutrino physics,
neutrinoless double beta decay
(NDBD) - a rare, lepton-number
violating, nuclear decay process –
is of particular current interest. The
observation of neutrino oscillations
demonstrated that neutrinos have
mass; a consequence of this new,
beyond the Standard Model physics
is renewed activity in NDBD
experiments which provide the only

nature of the neutrino (Dirac or

experiments offer the possibility of
determining the absolute neutrino
mass scale.
An international collaboration is
currently constructing a nextgeneration experiment, SuperNEMO,
This year has seen delivery of our
flight hardware for the European
Space Agency LISAPathfinder
mission. This mission will be
launched next year (2015) and it is
a technology precursor for the ESA
L3 mission in gravitational waves.
ESA recently selected the
gravitational wave theme for L3 and
this represents the successful
culmination of two decades of work
in developing the technology and
promoting the pioneering new
science opportunities in the fields of
astrophysics, cosmology and
particle physics. Following the
completion of our ZEPLIN direct
dark matter search programme we
now moved on with collaboration on

We have been working in a multidisciplinary team with members of
the Faculty of Medicine on the
development of new approaches to
proton therapy. We have identified
three different applications of our
expertise, namely proton
acceleration using laser-plasma
technology [1], proton delivery using
the FFAG technology [2], and
evaluating the effects of proton
therapy combined with new
metabolic drugs like ADI-PEG20.
We extended our work towards
modern challenges in medical
diagnostics, like the worldwide

more sensitive run at the moment.
In addition the LUX-ZEPLIN project,
which we co-founded in 2008, has
gone through an extensive design/
R&D phase and has been selected
as one of two next generation direct
dark matter search projects in the
US. The UK is intending to provide a
significant share of the experiment
with Imperial playing key roles, and
an application for funding is ongoing.

my group have been searching the
data taken by the CMS experiment
at the LHC for evidence of new
particles predicted by the theory of
Supersymmetry. So far no evidence
has been found and we have two
papers in preparation, which will
complete the searches with the
available data, and set stringent
limits on the allowed theoretical
parameter space.
The other focus of my work is
preparations for the restart of the
LHC at higher energy and
luminosity in 2015. To fully benefit
from the improved performance of
the LHC the CMS experiment must
be upgraded and working with
colleagues from Bristol, STFC and

improved triggering system for the
experiment. This will benefit our
searches for new physics, with
exciting prospects for the new run

muons—whose existence we have
known about for many decades—
the detailed behaviour of which can
yield more hints about the nature of
the fabric of our Universe. I have
worked on the T2K neutrino
oscillation experiment since 2004,
and in the past few years we have
discovered that muon neutrinos can
turn into electron neutrinos, which in
turn unlocks a new set of possible
measurements to search for matterantimatter differences in neutrinos.
This shapes our ongoing T2K work,
and work towards the nextgeneration Hyper-K experiment. For
the latter, I have contributed a new
idea for how to calibrate the
neutrino detectors.
I am also working on the COMET
experiment, where we will make
about 10 muons over a few years,
to see if some convert to an
electron. This cannot happen under
physics as we understand it now—
but is quite difficult to exclude when
we try to extend this
understanding—hence is an
extremely sensitive indicator
towards the next step in modelling
the Universe. COMET Phase-I is
due to turn on in the next couple of
years, and our group is working
hard on building the experiment.

My research probes the most
fundamental aspects of the nature
of matter and energy. In particular, I
am engaged in the study of neutrino
flavour oscillation, which is the
first—and so far only—discovery
that lies outside the current
predictions of the standard model of
particle physics. I work on
accelerator neutrino experiments,
currently focussing on the T2K
experiment in Japan.
T2K sends a beam of muon
neutrinos from the J-PARC facility in
Tokai-mura across the main island
of Japan to the Super-Kamiokande
detector deep within the Kamioka
mine. We have recently published
a stunningly large excess of
electron neutrino events allowing us
to measure the heretofore
unobserved subdominant oscillation
and its mixing angle, theta_1-3.
These are the next steps toward the
goal of searching for violation of
charge-parity symmetry with
I am also a member of the HyperKamiokande collaboration, which is
working toward a megatonne scale
water Cherenkov detector. This
experiment would provide exquisite
sensitivity to the search for violation
of charge-parity symmetry in
neutrinos, which could explain why
the universe is made of matter and
not antimatter.

The Photonics Group conducts fundamental research into optical science and develops and applies new
technologies for the physical and life sciences, medicine and ICT. Our projects are mostly interdisciplinary and we
work closely with industry and external agencies.

We conduct a world-leading research
activity on fibre and all-solid-state
lasers developed for many real-world
applications from precision laser manufacturing, remote sensing through to
medical imaging and therapeutics.
Fibre Lasers
This activity is currently focused on
development of compact and high
power fibre laser sources, engineered
to create new wavelengths and ultrashort pulse formats including: supercontinuum generation in photonic
crystal fibres; visible fibre sources by
Raman or parametric conversion of IR
fibre-lasers; near and mid-infrared
sources based on novel Bismuth and
Thulium-doped fibre lasers; ultrashort
pulse generation using carbon nanotubes or graphene as ‘universal’ saturable absorbers that can operate
across all wavelength regions.
Diode-Pumped Solid-State Lasers
This activity develops all-solid-state
lasers and nonlinear optical technologies to provide efficient sources of
high energy pulses including: diodepumped micro-slab lasers (commercialised by Mike Damzen’s spin-out
company, Midaz Lasers Ltd); worldleading diodepumped Alexandrite
lasers, supported by the European
Space Agency (ESA) for next-generation satellite-based remote sensing
and future femtosecond laser applications; and resilient “selforganising”
lasers based on dynamic nonlinear
optical holography that selfcorrect for
thermally-induced aberrations in high
power lasers.
a) fibre laser supercontinuum source; b) satellite-based remote sensing laser application
imaging for high content analysis and
sensing and manipulating pathogenic
bacteria. We have particular strengths
in fluorescence lifetime imaging
(FLIM) for quantitative molecular contrast, including of protein-protein interactions, superresolved microscopy
(including STED, PALM and STORM)
for imaging below the diffraction limit,
and confocal Brillouin scattering
microscopy to measure
the micromechanical properties of biological tissues. Our fluorescence
imaging and measurement technology
is being applied in hospitals to clinical
diagnostic challenges for cancer,
osteoarthritis, heart disease and ophthalmology and to preclinical tomographic imaging of disease models.
Programmable light
Building on our heritage of computerbased optical design, we utilise adaptive optics and structured illumination
to manipulate optical wavefronts for
applications ranging from ophthalmology to metrology of astronomical
optics, exploiting segmented mirror
and spatial light modulator technologies. For imaging
we use structured illumination to
realise wide-field optical sectioning
(with Mark Neil’s spin-out company,
Aurox Ltd) and adaptive optics techniques to measure and correct aberrated wavefronts, including for in vivo
studies of the retina for ophthalmology. Non-imaging applications of programmable light include precision
opto-genetics and optical tweezers.

Rigorous electromagnetic theory and
experimental analysis is applied to
photonic and nanophotonic structures
such as chiral media and metamaterials. The theoretical development of
“space-time cloaking” was founded in
our group; ultrahigh-resolution micropolarimetry is being applied to plasmonics, metamaterials, micromagnetics and to optical data storage
using polarisation to encode multiple
bits into each pit of an optical disc.

Alexandrite laser”, A.Teppitaksak, A. Minassian, G. M. Thomas, and M. J. Damzen, Optics

We have performed the world-first
high power development of diodepumped Alexandrite as a new laser
technology with broad wavelength
tunability [ref. 1]. This work is being
supported by the European Space
Agency as a new technology for
satellite-based remote sensing of
the atmosphere and ground
vegetation. It also has potential as a
low-cost replacement for the
femtosecond Ti-sapphire laser. We
have generated > 26W, more than
an order of magnitude higher than
previous diode end-pumping systems,
highest ever slope efficiency 49%, and
the first Q-switched laser operation
of diode-pumped Alexandrite
producing ~mJ-pulse energy at 1kHz
pulse rate in fundamental TEM00
mode. It was recently presented as
an invited Keynote talk at the Optical
Engineering and Design conference
and reported in trade journal [ref. 2].
We have also patented and
implemented a novel technique for
obtaining enhanced control of pulsing
parameters in a laser [ref. 3]. The
method uses a secondary laser cavity
to control the gain in a Q-switched
primary laser cavity and has enabled
clean single-pulse Q-switched
operation to be obtained across a
very wide repetition rate range of 1–
800 kHz and control of pulse energy.
In another project supported by Paul
Instrument Fund (Royal Society), we
are using liquid lenses, whose focal

The main focus of our work is the
application of photonics technology to
quantitative fluorescence imaging and
sensing. This includes collaborations
with clinicians that aim to exploit
endogenous tissue autofluorescence for the detection and
diagnosis of disease. Currently, we
(PF&CD) have an EPSRC funded
project with the National Heart and
Lung Institute and the Kennedy
Institute for Rheumatology to apply
point-probe and endoscopic
measurements of fluorescence
lifetime to study of heart disease
and arthritis. We also have a second
EPSRC funded project
(CD,PF,MN&CP) in collaboration with
the University of Bath to develop
novel multiphoton microscopes and
endoscopes for clinical applications.
Our technology (PF&CD) is also
applied to measurements of
exogenous fluorophores, for e.g.
quantification of photosensitiser
penetration with Moorfields Eye
Hospital, or in cells through
fluorescence lifetime imaging of
protein-protein interactions, including in
multi-well plate formats. We also have
projects developing optical
superresolution techniques
(PF,MN&CD) including stimulated
emission depletion microscopy. A
recent collaboration with colleagues at
King’s College London and the
Department of Bioengineering at
Imperial has translated optical
methods for superresolution imaging
to ultrasound superresolution
imaging, including in vivo, for the
first time. Finally, we continue to
develop a high speed 3-D
fluorescence microscopy technique
called oblique plane microscopy.

Professor Paul French
In the last year I have continued to
develop and apply multi-dimensional
fluorescence imaging technology,
particularly for super-resolved
microscopy (SRM), high content
analysis (HCA) and preclinical and
clinical imaging, in close collaboration
with Chris Dunsby, James McGinty,
Mark Neil and Carl Paterson. All of our
projects are inherently multidisciplinary
with collaborations across College
and beyond. With respect to SRM,
we (with CD, MN) are funded to work
with the MRC Clinical Sciences
Centre to develop 5 advanced SRM
instruments for the study of cellular
structure and function beyond the
diffraction limit. For HCA, we (with
CD) are developing automated
multiwell plate readers incorporating
fluorescence lifetime imaging (FLIM)
technology to assay protein
interactions and cellular metabolic
processes. We are also developing
open source software tools for
automated acquisition, rapid analysis
and management of image data –
particularly developing OMERObased tools in collaboration with the
University of Dundee. For preclinical
imaging we (with JM) are working
with Department of Life Sciences
and UCL to develop a platform
longitudinal imaging of whole zebrafish
from larvae to adults, which is being
applied to studies of cancer,
inflammation and bacterial infection.
For clinical imaging we (with CD)
are working on the application of
novel instrumentation to measure
autofluorescence lifetime for readouts
of heart disease and osteoarthritis
and (with CD, MN, CP) are working
on a compact handled multiphoton
microscope and an ultranarrow
multiphoton endoscope exploiting
adaptive optics to eliminate need for
distal scanning or focussing systems.

My work on ultrafast nonlinear fibre
optics is conducted in close
collaboration with Prof. Roy Taylor
and Dr. Sergei Popov and is a key
theme within the Photonics activity
at Imperial. Our shared interest in
the development of high-brightness,
short-pulse fibre laser sources for
target wavelengths in the visible
and mid-infrared is supported by
industrial collaborations with IPG
Photonics Inc. and Gooch and
Housego PLC, and is focussed on
bio-photonic specific applications –
lead by Prof. French.
My interest in power-scaling modelocked fibre lasers has led to
research studying the formation and
stabilisation of dissipative solitons
and involvement in a project run my
the University of British Columbia:
using such lasers as seed-sources for
frequency upconverted systems
based on high-harmonic generation in
passive femtosecond enhancement
cavities, providing a source of
synchrotron-level energy XUV for
table-top ARPES experiments.
I also continue to work closely with the
Graphene Centre at the University of
Cambridge on the fundamental study,
and application of low-dimensional
materials in ultrafast optics, recently
broadening the scope of this study
– through a collaboration with
Nanjing University, China – to
include graphene-enabled
plasmonic devices.
Additionally, diversification of
theories and models applied widely
in my research in optics has led to
collaboration with the Swinburne
University of Technology, where
nonlinear Schrödinger-type equations
are applied to understand the dynamics
of deep ocean waterwaves. In
particular, modulation instability and
the formation of rogue solitons have

Our recent research has sought to
understand some of the
implications of our introduction of
the so-called Spacetime cloak in
2011. This new type of cloak was
based on a radically novel
interpretation of transformation
optics which allowed the
concealment of events rather than
objects. It was subsequently
demonstrated experimentally. We
have studied how event cloaks can
be designed for simple wave
systems, and have examined their
directional nature – events
concealed in one direction are
visible, but distorted, in another.
We have considered applications in
optical processing, where an
to cm sized volumes is optical
projection tomography (OPT). OPT
is the optical analogue of X-ray CT,
where wide-field images of a
transparent sample are acquired
while the sample rotates. I have
been working on improvements to
enhance both the spatial resolution
and light efficiency while minimising
the acquisition time. The condition
for transparency can be realised for
ex vivo samples by chemical
clearing processes – essentially
exchanging the water in the sample
for a liquid of higher refractive index
that matches that of the tissue and
therefore suppresses the scattering
of light. For in vivo imaging,
samples that are inherently
transparent can be used, for
example the nematode worm and
the zebrafish embryo (∼mm scale).
In addition to producing 3-D
structural reconstructions, I am also
translating the quantitative
techniques applicable in
microscopy to OPT. In particular I
am working on techniques to realise
time-lapse 3-D imaging of dynamic
processes and fluorescence lifetime
imaging for measuring protein
interactions using Förster
resonance energy transfer.

The work of the Femtosecond
Optics Group is directed towards the
development of spectral and
temporal versatility in fibre based
sources with the objective of
applications and potential
Compact, short pulse, moderate
average power (~10s W), fully fibre
integrated, chirped pulse, masteroscillator power fibre amplifier
configurations are being developed,
with the emphasis on Yb-doped
systems for operation in the 1 μm
window. Following first stage pulse
compression in conventional grating
pairs, generation of pulses ~100s
femtoseconds allows further
compression in gas filled photonic
crystal fibre grating assemblies to
pulses ~10s femtoseconds that can
be applied to non-linear conversion
studies in gases, allowing tuneable
uv generation. Extension of the
technique to Tm based fibre
assemblies has supplied moderate
average power, femtosecond pump
pulses for broad band supercontinuum
generation in the 2-3.5 μm range in
silica based fibres containing a high
Germania content. With planned
power scaling, through initial pulse
compression spectral coverage up to
5 μm should be possible.
Broadly tuneable visible generation
in compact all fibre configurations
has been achieved through using
frequency-doubled, laser-diode
seeded, single-pass cascaded
Raman generation in integrated
silica fibre assemblies. With near
infra-red pumping, highly efficient
optical parametric generation in
photonic crystal fibres has also
allowed spectral generation towards
visible wavelengths.
In collaboration with Polytechnique
Montreal pulse compression of
pulses from giant chirped pulsed
fibre lasers has been demonstrated
in long ( up to 0.5m) chirped fibre
Bragg gratings, confirming
theoretical models on the
performance of this unique class of

Plasma Physics
We are one of the largest plasma physics groups in the world, and deal with plasmas ranging from the low
densities and temperatures found in industrial processes to the extreme conditions at the centre of a laser driven
capsule of fusion fuel or the core of a star. The group's research links experiments, many performed on in-house
facilities to complex theory and numerical simulations using super computers. We also host the Centre for Inertial
FusionStudies which connects high energy density science to the search for fusion energy production, and the
Institute of Shock Physics which creates and studies materials and systems under extremes of pressure.
S Lebedev, RA Smith, J Chittenden,
S Bland, F Suzuki-Vidal.
We build and operate multi-terawatt
(1012W) electrical machines and
short-pulse lasers to create and study
exotic plasma conditions. The group’s
1.4 million amp Z-pinch MAGPIE is
the largest open-access machine of
its kind in the world and linked to the
UK's largest University based laser
system Cerberus. MAGPIE allows us
to creates plasmas from arrays of
wires or foils and then accelerate or
‘pinche’ them with strong magnetic
fields. We use this to launch high
speed ~100 kms-1 plasma jets or
shock waves which simulate astrophysical processes such as star
formation in the laboratory.
The group’s experimental work is supported by complex computer simulations using tools we develop such as
the 3D Magneto-hydrodynamics computer code GORGON. This is now
used to simulate plasma dynamics in
experiments in laboratories across the
world including the 26 mega-amp Z
facility in the US. Gorgon is also used
to simulate complex laser based
experiments such as the stability of
NIF inertial fusion implosions.
Z Najmudin, S Mangles, RA Smith, R
The group creates and studies high
energy density plasmas using powerful lasers, both at Imperial and major
laboratories worldwide. Lasers can
accelerate particles to very high energies over remarkably short distances
and we have produced GeV electron
beams in just 1 cm of plasma. These
beams can be used to create ultrabright x-ray sources and could one
day replace low energy synchrotrons.
We have used them to trial new applications including medical imaging and
we are also exploring similar laser
driven techniques for cancer therapy,
where the short stopping distance of a
proton beam may be used to target
tumours with low collateral damage
and high precision.

Compressing and heating a mix of
hydrogen isotopes can lead to thermonuclear fusion and potentially a
huge energy release that might one
day underpin a new generation of
power stations. In fusion ignition
experiments the plasma density and
temperatures created far exceed
those at the centre of the sun.
Through experiment and computer
simulations we study both fundamental plasma processes at these conditions, and advanced fusion concepts
such as "fast ignition" and "shock
ignition" that may allow us to reach
"breakeven", the point where more
energy is released from the plasma
than required to heat and confine it.
The tools and concepts we develop
for inertial fusion research also allow
us to study in the laboratory scale
models of some of nature's most
extreme phenomena. In "laboratory
astrophysics" experiments we probe
the formation of accretion disks
around black holes and the dynamics
of supernova explosions.
M Coppins, S Cowley, M. Lilley
We investigate magnetic confinement
fusion using a doughnut shaped
Tokamak, in which a low density
plasma is held inside strong magnetic
fields and heated over multiple seconds with a combination of electric
current, microwaves and particle
beams. The world’s largest and most
successful Tokamak JET is based at
Culham, along with a more compact
machine, MAST.
Tokamaks are affected by dust, small
grains of solid material that are carried
along with the plasma. Dusty plasmas
occur naturally in space and are also
found in industry and affect the production of materials and components.
We study them because of their
potential to trap radioactive tritium and
disrupt future magnetic fusion test

demonstrates the ability to

could provide a new probing

On the MAGPIE facility a series of
experiments examined the
production of radiative shock waves
within gas filled cylindrical liners,
and how the application of a
magnetic field affected their
dynamics (1). Such experiments
could influence the design of
magnetised inertial fusion targets,
and in collaboration with
Loughborough University a 10Tesla
magnetic field system is being
developed to aid experiments.
A new method of isentropically
compressing a cylinder of material
to extreme pressures (>>Mbar) has
been explored (2). Critically this
technique produces large volumes
of compressed material, held at
pressure for many ns, hopefully
enabling phase changes – e.g.
metallisation of hydrogen – to occur.
The technique is presently being
examined at Sandia National labs.
Working with colleagues at CEA
Gramat, an ‘X-pinch’ system has
been developed to provide X-ray
diffraction measurements of
materials being dynamically
compressed (3). In a separate
series of collaborations with the
CEA and ESRF, a low energy (50J)
laser was used to drive very small
samples of iron to MBar pressures,
whilst the high precision, micron
sized X-ray beam from the
synchrotron was used to explore the

20MA generator at Sandia National
Laboratory. We have adapted this work
to develop new techniques for
isentropic compression of materials
which can be used to recreate the
extreme conditions at the centre of gas
giant planets. We are also utilising
kinetic models of the fast particle
species within these plasmas to study
the generation of K-alpha photons by
runaway electrons, the generation of
secondary nuclear fusion reaction
products, beam-target reaction
processes due to runaway ions and
the ignition of a fusion plasma by
energetic alpha particles.

detailed analysis of the distribution of

Our work on dusty plasmas
concentrates on the basic physics
of the dust-plasma interaction, and
dust in tokamaks. We collaborate
with John Allen (Oxford), Umberto
Department of Physics Review 2013 -14
deAngelis (Naples), and Alex
Robinson (RAL). On the basic physics
side, three topics can be mentioned
from the last 12 months. Firstly, we
have found the equilibrium charge
distribution for large (i.e., larger
than a Debye length) dust grains
[1], due to fluctuations in the charge.
Secondly, the planar source-sheath
configuration has been studied
computationally and theoretically
[2]. Although dust is not directly
involved, results from this work
have subsequently been used to
construct a new model for the
charging of large dust grains.
Thirdly, the charging of small dust
grains in a flowing plasma, and the
formation of associated structures
in the surrounding plasma, has
been studied using kinetic theory
[3]. In contrast to the large grain
case, we find upstream structures.
In the other area, dust in tokamaks,
we are currently preparing a paper
on hypervelocity dust [4], i.e.,
particles with speeds > 1.0 km/s
which have been reported in some
tokamaks. It has been suggested
that such particles may significantly
damage the vessel walls. Our
studies indicate that this is not the

Our recent work focuses on theory and
simulation of high-power laser-plasma
interaction, in the context of Inertial
Fusion Energy and High Energy
Density Plasmas. We have been
developing and using a new
computational approach for calculating
transport of laser-generated relativistic
electron beams for igniting precompressed fuel. Our semi-kinetic
treatment of the background plasma,
including magnetic field, has revealed
new mechanisms capable of altering
beam propagation. In collaboration
with colleagues at the University of
York and LLNL, we are using our
Vlasov-Fokker-Planck codes to
validate and improve the heat flow
model used in radiation-hydrodynamic
codes, for improved modelling of the
NIF. We continue research into the
dynamics of under-dense plasma
heated by nanosecond laser beams.
We have extended our magnetothermal instability to include both
hydrodynamics and non-equilibrium
thermodynamics due to nonMaxwellian electron distributions. To
get a complete self-consistent
description of the entire system,
refraction and filamentation of the laser
beam has been added. We are
collaborating on several, multiinstitutional laser experiments at UK
laser facilities (Vulcan and Orion) to
explore this complex physics

My research focuses on the
development and exploitation of
advanced laser sources to produce
ultra-short and ultra-high-intensity
light pulses. We use these to
create and probe exotic states of
matter, ranging from laboratory scale
simulations of supernova remnants
and plasma jets launched during star
formation through to the subfemtosecond dynamics of
nanometer scale "clusters" of
atoms. To underpin our
experiments we operate the UK's
largest University based laser
Cerberus, which delivers high
energy ns and sub-ps pulses to
multiple experimental areas.
Cerberus is also linked to MAGPIE,
one of the world's largest Zpinches. This combination of
pulsed power and laser systems
allows us to explore the complex
behaviour of high-energy-density
plasmas in which huge magnetic
fields play a dominant role. We
also develop new types of target for

precision in vacuum. We have

probes to measure the distribution of

The Institute of Shock Physics
Over the past few years the Institute of Shock Physics has established a diverse research profile probing the
response of condensed matter under ultra-fast and extreme compression. These necessarily multi-scale, multidisciplinary studies require both experimental and computational activities extending to MBar pressures,
intermediate to very high strain rate regimes, and from kilometers to sub-micrometer length scales. Supported by
a unique suite of state-of-the-art experimental facilities the institutes’ research activities understanding
fundamental processes occurring in materials under extreme conditions, find relevance to a wide range of
applications in both natural and man-made environments; from fusion technologies to astrophysical events such
as interplanetary impact.

Synchrotron X-ray Studies of
Extreme Processes
Dr Daniel Eakins, Dr David Chapman
We are developing a new capability for
the X-ray imaging of extreme physical
processes which leverages the brilliance of third generation light sources.
Classically our understanding of materials under extreme conditions is
determined indirectly using non-penetrating diagnostics (visible light); the
use of X-rays provides a unique
opportunity to probe within a material
while it is dynamically loaded, to
directly study its equation of state,
strength and failure properties.
By integrating a purpose-built impact
system with the I12 high-energy
beamline at the Diamond Light
Source, we have performed the first
experiments involving time-resolved
synchrotron X-ray imaging of dynamic
compression in high-Z materials. This
pioneering experimental work will enable
more faithful macroscopic representation
of statistical microstates in heterogeneous systems, the study of shock
energy localization during instability
growth, and direct density probing of
material states under extreme conditions. The team also collaborates
internationally participating in dynamic
X-ray experiments in both Europe and
the US. A recent highlight is the
involvement in the first EXAFS experiment on Fe driven to Mbar pressures
using a high-power laser at the ESRF.
Royal British Legion Centre for
Blast Injury Studies
Dr William G Proud
CBIS conducts research into understanding the process of blast injury on
people. It has strong links to the Institute
of Shock Physics. The institute has
designed and instrumented a range of
loading devices for the centre including shock tubes and Split Hopkinson
Pressure Bars (SHPB).
Our overall aim is to ensure that the
loading conditions on these complex
materials are understood and are in
the correct pressure-time space for
blast processes.
Two specific research projects highlight
the synergistic nature of the interaction.
(a) examining the effect of representative pressure pulse from the blast
waves on STEM cells. The SHPB was
used to provide the loading and a
sample cell was developed which had
to be fully calibrated mechanically, able to
withstand the pressures imposed on it
and also be biologically inert. The
results indicate that pressures as low
as 100 atmospheres for 100 microseconds can result in the destruction of
10% of STEM cells. The debris from
these cells is biologically active and
may cause longer term pathologies
(b) Modifying the output of the Shock
Tube to produce the blast loading seen
from a range of explosive masses, over
distance through a variety of mitigation. This required precise control of
the shock tube operation. As a result
of this we can produce blast loadings
equivalent to 25 kg of TNT at 2 m distance or, at the other extreme, the
loading produced inside a vehicle from
a small external charge.
Pulsed Power driven High Pressure
Physics Experiments
Dr Simon Bland, Dr Jeremy Chittenden
We are developing a series of new
capabilities to drive matter into high
pressure states without the use of
shock waves. Such capabilities allow
new areas of the equation of state to
be explored, enabling low temperature
phase changes to be examined and
provide the basis for studying the
cores of giant planets planetary cores.
The new 2 Mega-Ampere current generator, MACH, has recently begun
operations, demonstrating methods of
tailoring the pressure drive onto an
target. Simultaneously the use of convergent targets, to significantly
increase the available pressures, has
been explored using the world leading
Gorgon MHD code. To directly probe
the states produced in these experiments, a new, ns timescale, multi-KeV
X-ray source is being developed with
colleagues at CEA Gramat. Already
this source has been used to demonstrate X-ray diffraction and future
experiments will explore its use in Xray absorption spectrometry.

My research is directed toward the
mechanisms of deformation in
condensed matter at extreme
strain-rates, from the bulk to submicron scale. I focus on the
transition between elastic and
plastic behaviour, with specific
attention to the processes of
ultrafast inelastic deformation
(defect generation, plasticity,
localisation, fracture, etc.). My work
seeks to resolve the relationship
between the structure of solid
phases and their pathway through
various defect states, from the early
moments of loading to their bulk
conclusions. Within this area, I am
presently working on the effect of
alloying and other impurities on
ultrafast elastoplasticity, new
analytical methods for simulating
true dislocation dynamics under
dynamic loading, and the
temperature dependence of
dynamic fracture mechanisms.
My work also involves the study of
heterogeneous materials, and the
statistical representation of nonuniform material response at
various microstructural levels. This
area extends my earlier work on
powder systems into new territory
through the coupling of novel
experimental techniques and
spatially-resolved diagnostics with
2D/3D numerical simulation. One of
the primary drivers for this work is
to establish a “Materials by Design”
theme, whereby improved

My personal research is best
summarised as:(a) the high-rate
loading of granular and piezo-electric
materials, determining how their nonlinear behaviour changes with stress
level, load duration, strain-rate, and
temperature (b) optical effects of shock
in birefringant materials to develop a
fundamental understanding of nonisotropic materials (c) biological and
other soft materials under blast and
impact loading. I also retain a string
interest in energetic materials. The
references below are relatively brief
conference papers, more detailed
articles can be found visiting the
Institute of Shock Physics Website.
The area of shock physics is multidisciplinary and this research has
progressed quickly thanks to
colleagues in bio-engineering, civil
engineering, medicine, materials
science and earth sciences and
engineering. I am closely involved with
the management and research
direction of The Royal British Legion
Centre for Blast Injury Studies and the
Institute of Security Science and
Technology, both of which are
stimulating and vibrant research
centres cutting across traditional
research boundaries.

This major grouping of experimental
and theoretical physicists is concerned with the interaction of highintensity and ultra-short laser pulses
with matter.
Attosecond (As) Science We are pioneering new methods to measure
electron motion in matter in real time.
Through this we are learning how
electrons move inside molecules and
solids on a timescale of ~100 As vital
for revealing the correlations in many
electron quantum systems. Ultrafast
science with X-ray free electron
lasers Free electron lasers are opening new frontiers in the imaging of
matter at the nanoscale with full time
resolution. We are studying ways to
make few-fs time resolved measurements using these instruments.
Development of ultrafast, high power,
laser sources. The group has pioneered the development of new
sources including high power fiber
based systems. High energy density

group this research uses various

Cold atoms and Molecules: We use
the techniques of laser cooling and
trapping to control and manipulate
matter onto microchips (Atom chips)
at temperatures a few billionths of a
degree above absolute zero . With
these devices, we aim to build ultra
precision sensors and components
for quantum information processing.
Ultracold molecules offer new opportunities because of increased
degrees of freedom and because
they interact strongly with applied
electric fields and with one another,
allowing for the study of the physics
of strongly-interacting many-body
quantum systems. Electron electric
dipole moment We measure the
shape of the electron – its electric
dipole moment. This is a test of
physics beyond the Standard Model
of particle physics and a test of timereversal symmetry violation.
Quantum nanophotonics Single photons are the essential building blocks
for photonic information processing.
We use single organic dye molecules
at cryogenic condition because they
can serve as an efficient source of
indistinguishable single photons.
Bose-Einstein condensation of photons At low temperature and high
density, the properties of a fluid
depend on the quantum nature of its
constituents, whether they are
bosons or fermions. Bosons tend to
bunch together, and in extreme
cases form a giant wave called a
Bose-Einstein Condensate (BEC).
We are making a room temperature
BEC of photons. Our aim is to understand how photon BECs form, study
their properties and their interactions.
Ion traps Here we test the predictions
of Quantum Electrodynamics (QED)
using highly-charged ions and also
investigate the fascinating physics of
"ion Coulomb crystals", which can be
used in applications such as quantum simulation and studies of quantum tunnelling. We carry out our
experiments with a Penning trap,
which uses static electric and magnetic fields to confine atomic ions.
We use laser cooling to reduce the
temperature of calcium ions to less
than 1 kelvin and study the ions
using precision laser spectroscopy
and high resolution imaging of the ions.

The theoretical research interest of the
group is the control and manipulation of
physical systems to exhibit manifestly
quantum mechanical effects such as
quantum correlations and quantum
interference. The emphasis is on using
these effects to perform novel protocols
in e.g. quantum computing in hybrid
architectures, quantum communication
and quantum simulations or to uncover
the subtle role quantum mechanics may
play in natural phenomena. Our general
approaches can also be used, for
instance, to elucidate the role of fundamental symmetries in nature, as well as
metrology (precision measurement).
Finally, the study of controlled quantum
dynamics may lead us to new insights
in the foundations of quantum mechanics itself.

The main direction of out work has
been development and theoretical
modelling of time-resolved
attosecond spectroscopic
techniques for the study of ultrafast
electron hole migration in
molecules. We have suggested
several such techniques that are
now being at various stages of
experimental realisation: (1) singlephoton laser-enabled Auger decay
(spLEAD) spectroscopy of hole
migration, (2) high-order harmonic
generation spectroscopy of electron
correlation-driven hole dynamics, (3)
time-dependent Auger spectroscopy
of hole migration. In addition, we
have provided theoretical support
for one of the first two time-resolved
measurements of the inter-atomic
Coulombic decay in clusters. Finally,
we have developed the first of its
kind first-principles molecular
method for numerical modelling of
many-electron dynamics in strong

B-spline algebraic diagrammatic

macroscopic systems which is why
quantum mechanics was thought to
be applied only to a sub-atomic
system. Kim’s research interests in
the foundations of quantum physics
are concentrated on the issues of
the manifestations of wave-particle
duality and the quantum-to-classical
transition. Why is it not possible to
observe quantum superpositions
and nonlocality in everyday life? For
this question, he came up with a
possible solution based on
fuzziness in operations [1]. His
suggestion is in contrast to the usual
assumption based on decoherence
and coarsening of measurements.
He then considered another
fundamental problem in relation to
the wave-particle duality and the
impact of measurements on this [2].
The quantum-mechanical
superpositions are more easily
generated in an isolated system
such as a cavity. However, in order
to characterise and control the
superpositions, we need to bring
them out. He and his colleagues
show how those quantum states can
be taken out from the cavity in [3].

spins. We implemented a method
based on Lyapunov control in terms
of this description and designed
control fields that establish strong
entanglement in chains with ten
percent relative fluctuation in the
nearest neighbor interaction [4].

I have been working on improvements
to out experiment to measure the
permanent electric dipole moment
(EDM) of the electron, and on
experiments to directly laser cool
CaF molecules. While the EDM
experiment did provide the most
stringent limit on the size of this
time-reversal violating effect, it was
on the local density of matter, as
hypothesized in some extensions of
the Standard Model. We found no
dependence and set new bounds on
such variations of the constants [1].
We then extended this work to
precise measurements of millimetrewave transitions in CH [2]. These
transitions have been observed in
extra-galactic sources at high redshift, and so can be used to test
whether the fundamental constants
vary with time. Precise
measurements using molecules
benefit from cooling the molecules
to very low temperatures. We have
demonstrated that laser cooling, a
method commonly used to cool
atoms, can also be used to slow and
cool a beam of CaF molecules [3].
We then analysed how laser cooling
can be used to make a magnetooptical trap of these molecules [4].

My research within the Blackett
Laboratory Laser Consortium is
concerned with Attosecond Science

into three interconnected themes: i)
the development of state-of-the-art
ultrafast laser technology, ii) the use
of these lasers to develop novel
short-wavelength (UV to X-ray)
coherent light sources, with focus on
Quantum Optics and Laser
those providing attosecond (10-18
sec) pulse durations, iii) the
application of i) and ii) to implement
novel techniques for tracking
attosecond time-scale electron
dynamics in matter. Recent work on
theme (i), in collaboration with LOA
Paris, has been a detailed study [1]
of the hollow-fibre pulse
compression technique used by labs
around the world to produce highpower laser pulses of durations
approaching 1 optical cycle.
Towards theme (ii), we have
demonstrated for the first time the
generation of synchronised VUV
and XUV attosecond pulses for
pump probe experiments, with
support from collaborators in
Hannover [2]. Also, we have made
the first spatial coherence
measurements of high order
harmonic radiation generated in
laser-ablated plumes [3]. A recent
highlight from theme (iii) is the first
measurement of temporal
broadening of attosecond
photoelectron wavepackets from
solid surfaces [4], in collaboration

Space and Atmospheric Physics
The group studies interplanetary space and planetary environments, as well as the Earth's atmosphere and oceans.
A major part of the group’s activity is the development and operation of numerical models and sensitive
instrumentation for space science and Earth observation.

Fundamental Plasma Processes:
Magnetic reconnection, turbulence, and
shock waves govern much of the
dynamics of plasmas, giving rise to the
transport of momentum and energy while
accelerating charged particles to high
energies in the process. Our internationally recognised leadership in understanding these fundamental plasma
processes employs spacecraft data,
theory and modeling. We lead the magnetic field instruments on important current spacecraft (ESA’s Cluster and
Cassini missions) and future missions
(ESA’s Solar Orbiter and JUICE). Applications of Space Plasma Physics: Interplanetary space is pervaded by a
supersonic solar wind emanating from
the Sun’s corona. Variability in that
solar wind, due to solar activity and
eruptions from the solar surface, often
termed “Solar Storms” leads to “Space
Weather” which can energise the Earth’s
radiation belts and lead to spectacular
aurorae. Space Weather also has a
huge impact on satellites and groundbased systems (e.g., electricity grids)
representing risks to vital services and
expensive infrastructure, and now forms a
major element in the national risk register.
Dr Marina Galand, Prof Michele
Dougherty FRS, Dr Ingo MuellerWodarg
Planetary research is focused on the
Cassini mission to Saturn and its
largest moon Titan, which has a dense
“Earthlike” atmosphere. The group
leads the magnetometer team and
investigates Saturn’s magnetosphere,
its plasma boundaries, as well as the
internal magnetic field of the planet. We
study planetary ionospheres, some, such
as Titan, hosting heavy organics, others,
such as at Saturn, playing a key role in
closing the global magnetospheric currents which arise. We study the upper
atmosphere of Saturn using our Saturn
Thermosphere Ionosphere model. We
lead the Venus Express Atmospheric
drag experiment and use it to determine
the polar thermosphere structure at
Venus. We lead the operation of the
Plasma Consortium suite of instruments
on board ESA’s Rosetta mission to the
comet 67P Churyumov-Gerasimenko.
We lead the magnetometer team on
the JUICE (Jupiter Icy Moons Explorer)
mission to Jupiter and its icy moons
and are designing the instrument in
order that it can resolve induced currents
flowing in the liquid water oceans at
Ganymede, Callisto and Europa.

Modelling: We study the physical
processes and composition in the
atmosphere and ocean using idealised,
regional and global models (e.g.
HadGEM, NASA GISS). Key expertise
lies in the impact of key physical
processes on our climate system, such
as solar variability, the coupling of tropical and extra-tropical storms with the
ocean, the impact of changes in atmospheric composition on radiation and
precipitation, and the role of fires in the
Earth System.
Earth Observation: Scientific lead for
the Geostationary Earth Radiation
Budget (GERB) project, the only instrument to observe the broadband energy
emitted and reflected by the Earth at
high temporal resolution. GERB data
are used to quantify, the diurnal variability in Saharan dust net radiative
forcing at the top of the atmosphere,
the surface, and within the atmosphere.
Our Tropospheric Airborne Fourier
Transform Spectrometer (TAFTS) participates in national campaigns to
assess the radiative effect of cirrus
clouds across the electromagnetic
spectrum, again with the ultimate aim
of using observations to improve modelling capability. Satellite observations
from instruments such as the Tropospheric Emission Spectrometer (TES)
and Infrared Atmospheric Sounding
Interferometer (IASI) play a vital role to
better understand feedbacks operating
in the Earth system. A new activity
relates to the carbon cycle via measurements and modelling of atmospheric
CO2 and CO2 isotopes.
Chris Carr, Dr Helen Brindley,
Dr Heather Graven, Dr Juliet Pickering
Our research is underpinned by instrumentation projects for spaceflight,
research aircraft, and in the laboratory.
Our magnetometers fly on the Cluster,
Cassini, Solar Orbiter and JUICE missions. the Plasma Consortium instrumentation on the Rosetta mission, and
the GERB instruments for the Meteosat
2nd Generation spacecraft. In the laboratory, our unique visible-vacuum ultraviolet Fourier Transform Spectrometer
studies atomic and molecular spectra
of importance for interpretation of spectral measurements of planetary
atmospheres and astrophysical objects. Measurements of atmospheric CO2
and its isotopic composition
are being developed to
study anthropogenic emissions and their impacts on
the global carbon cycle.

Efforts in my group have recently
focused on understanding how
warm and fast ocean currents such
as the Kuroshio and the Gulf Stream
impact on storms and atmospheric
motions of larger scales in the extratropics. Using a combination of high
resolution numerical experiments
(UK Met Office Model) and
atmospheric reanalysis data (ERA
interim, 1979-present), we have
shown that the Gulf Stream affects
both the cold and warm sectors of
cyclones, although with very
different mechanisms (shallow
convection and moist inertial
instability, respectively). We have
also shown that atmospheric heat
transport in the storm track is
sporadic in nature, with a large
contribution to the mean arising
from shirt-lived and extreme bursts
of heat transport.

My research currently centres on
understanding how magnetic
reconnection across current sheets
in collisionless space plasmas
works. This process lies at the heart
of many solar, space and
astrophysical plasma phenomena
such as solar flares and
geomagnetic storms. Working with
postdoc Dr. Heli Hietala and PhD
student Rishi Mistry, and in
collaboration with UC Berkeley, the
University of Maryland, and the
University of Delaware, we have
recently published new research
Department of Physics Review 2013 -14
showing for the first time how the
energy explosively released by
reconnection is partitioned, and
demonstrating how reconnection
can operate in a bursty fashion over
a prolonged period of time.
This work is intimately related to the
applied science of space weather,
which represents a threat to
infrastructure resilience and is now
included on the UK national risk
register. In collaboration with the
plasma physics group (Prof. Jerry
Chittenden), and PhD student Lars
Mejnertsen we have adapted the
Gorgon computer code (used for
laboratory plasmas) to simulate the
solar wind-magnetosphere
interaction, most recently using the
DiRAC high performance computing
facility. These simulations, informed
by our group’s research into the
underpinning physics, will be both
useful for interpreting satellite
observations and are directly
relevant for improving future space
weather forecasts.

We have developed a new expertise
and led original work in the active field
of cometary plasma in relation with the
on-going ESA/Rosetta mission which
reached its target, comet 67P, in
August 2014. We have been closely
involved in this mission through the
Rosetta Plasma Consortium (RPC)
and the Rosetta Orbiter Spectrometer
for Ion and Neutral Analyzer (Rosina).
We have pursued our research on
Titan’s complex ionosphere using multiinstrumental dataset from the Cassini
spacecraft. We have in particular
identified a key role played by negative
ions unexpectedly discovered in Titan’s
deep ionosphere. This work was
performed with colleagues from Europe
(France, Sweden, UK) and from
University of Arizona. We have also
continued our participation to Saturn’s
ionospheric studies with application to
the ring rain and have led work on the
characterization of the acceleration
processes above Saturn’s auroral
regions. Our giant planet interest has
expended to the Jovian system – with
our involvement in the plasma package
and UV spectrometer onboard the
ESA/Jupiter Icy Moon Explorer (JUICE)
– and to exoplanets under stellar
radiation. In collaboration with
colleagues from Boston University we
have broaden our expertise of CO2dominated atmospheres from Venus to
Mars, with original work applied to the
plasma heat budget.

My research focuses on
atmospheric CO2 and the global
carbon cycle. I study the influences
of fossil fuel combustion and natural
exchanges with the ocean and
terrestrial biosphere on CO2 by
combining observations and models
in regional and global-scale studies.
In a recent paper in Science we
showed long-term changes in the
observed seasonal cycle of CO2
concentration. The observations
show a 50% increase in the
amplitude of the seasonal cycle,
reflecting changes in northern
ecosystems that are much larger
than predicted by current IPCC
Department of Physics Review 2013 -14
models. Before joining Imperial in
late 2013, I began a collaborative
project to study CO2 fluxes from
fossil fuel emissions and biospheric
exchange in California with a grant
from NASA’s Carbon Monitoring
System. I was also awarded funding
from the European Commission and
the Royal Society in 2013-14. I am
developing new collaborations in the
UK with researchers at Imperial and
at the University of Oxford,
University of Bristol, Queens
University Belfast, and the
University of East Anglia. Themes
that will be explored involve the
oceanic sink of CO2 and its
sensitivity to ocean circulation
change, and development of
innovative atmospheric observations
to distinguish anthropogenic from
natural influences on the carbon

My work concerns how variations in
solar UV radiation influence the
structure of the stratosphere3 and how
changes in the stratosphere influence
the climate below1. Measurements
from the SORCE satellite suggest
larger solar cycle trends in UV than
previously thought and we have shown
that they imply very different impacts on
ozone and surface climate2. The
calibration of these data is being
continuously revised, and the
remaining lifetime of the satellite is
uncertain, while the successor mission
is not expected to launch until mid2017. With no other measurements
having the calibration required for the
investigation of multi-year trends there
will not only be a gap in the record but
also insufficient new data to confirm the
SORCE measurements. To address
this data gap, in such an important
climate variable, we have proposed a
new approach for measuring the solar
spectrum4. The basis of the method is
to take measurements of atmospheric
ozone, and other parameters sensitive
to solar irradiance, and to analyse
variations in these to deduce what
changes in the spectrum must have
produced them. To date we have
demonstrated the statistical methods
but not produced a robust change in
solar spectrum Nevertheless the
technique is promising and we are
developing new ways in which it might

Work initiated with a previous STFC
post-doc on the heating of electrons
at the bow shock located sunward of
the Earth’s magnetosphere has
reached a definitive, though
provocative conclusion. We showed
that the high mobility of the collision
free electron population together
with the curved nature of the bow
shock couples distant regions of the
shocked plasma (the magnetosheath).
The result, predicted based on
simulations and tested with data
from the Cluster and THEMIS
spacecraft, is that, despite the
strong variation in Mach number and
therefore total heating rate around
the bow shock, the magnetosheath
electron temperature is roughly
constant, implying a varying
proportion of heat taken up by other
species. The electron heating is
controlled by as yet unknown
processes that occur at the point
where the interplanetary magnetic
field first touches the bow shock,
i.e., where it is tangent to the
surface. Other work, with post-doc
Matteini, has explored the dynamics
of different solar wind ions in the
presence of interplanetary turbulence,

Theoretical Physics
The research of the Theoretical Physics Group covers a wide range of areas bound together by the theme of
fundamental questions in cosmology, gravity, particle physics, and quantum theory.
Duff, Gauntlett, Hanany, Hull, Stelle,
Tseytlin, Waldram, Wiseman
Within this subtheme we work on
the physical and mathematical
structure of string/M-theory as a proposed frameworkfor unifying the
Standard Model of Particle Physics
with General Relativity.
In addition, string/M-theory provides
deep insights into the non-perturbative structure of quantum field
The AdS/CFT correspondence,
which relates strongly coupled
quantum field theory to weakly coupled gravitational descriptions in
higher spacetime dimensions, is one
of the most profound discoveries in
string/M-theory and is a major focus
of the group. Our activities of the
Group in this area are supported
by two ERC Advanced Grants. One
is focussed on exploring integrability
structures present in particular systems. The second Is focussed on
trying to apply the AdS/CFT correspondence to poorly understood
strongly coupled systems that arise
in condensed matter physics, such
as the high temperature superconductors. The properties of black
holes play a central role in this work,
as they do in other areas of
research in this subtheme.
The Group also actively investigates
the very rich mathematical structure
of string/M-theory. This line of
research could lead to a precise
mathematical definition of what
string/M-theory is. It is also important in connecting string theory with
particle phenomenology and in
obtaining exact non-perturbative
results in quantum field theory. This
area is supported by an EPSRC
Programme Grant.

The principal objective in this subtheme is to discover ways of testing
innovative particle physics and
quantum gravity theories against
hard astrophysical data. A particular
strength of the Group is the leading
expertise in both theoretical cosmological models and the extraction of
phenomenology from the data.
We have made significant contributions to the inflationary theory of
cosmological perurbations, using
both analytical and lattice techniques. One focus is on the physics
arising at the end of inflation, particularly in relation to defect production.
Alternatives to inflation are also
investigated including cyclic universe models and varying speed of
light theories. Modified theories of
gravity obviating the need for dark
matter are another focus. The cosmology group has been pioneering
the extraction of phenomenology
from quantum gravity in several
guises and testing it against data.
On the more observational side, we
continue to work on the development and application of methods of
CMB data analysis, including
involvement in a number of experimental efforts such as Planck and

The Group also works on other
approaches to quantum gravity
including causal set theory, which
posits that spacetime is fundamentally discrete. The foundations of
quantum mechanics, including the
emergence of classicality, are investigated both in connection to low
energy phenomenology and to provide insights into the structure of
quantum gravity.
Evans Emeritus: Rivers
The group also has a keen interest
in statistical physics arising in classical systems. This ranges from applications of graph theory, to discrete
space times, to citation networks
and to studies of how spatial constraints alter the structure of networks, both in theoretical models
and in data from actual

trajectories from the Planck satellite

My research on the causal set
approach to quantum gravity continued
with the discovery of a family of
discrete non-local Lorentz invariant
D’Alembertian operators for scalar
fields extending results in 2 and 4
dimensions to all dimensions. I
continued my work on Foundations
of Quantum Mechanics with work on
characterising non-locality from the
perspective of a sum-over-histories
approach to quantum theory. We
discovered a strong connection
between a condition on sets of
experimental probabilities – a quantum
analogue of a non-contextuality
condition – that arises naturally in a
histories approach and a condition
that is known in the quantum
information literature as “Almost
Quantum.” We did work highlighting
the fact that a relativistic quantum
field theory lacks a set of rules
specifying what interventions by
external observers, including
measurements, are possible.
Restricting measurements and
interventions to those that do not
violate relativistic causality puts
constraints on the processing of
quantum information using quantum

Class. Quantum Grav. 30 195016
My recent work in collaboration with
Leron Borston and my students Alex
Anastasiou, Leo Hughes and Silvia
Nagy is devoted to finding a consistent
quantum theory of gravity. We
address the question of whether
gravity, a force traditionally described
by Einstein’s general relativity, can
be regarded as the product of two
Yang-Mills theories (quantum field
theories used in the standard model
of particle physics to describe the
strong, weak and electromagnetic
forces). There has already been
some progress in this direction at
the level of scattering amplitudes in
momentum space but our goal is
more ambitious. We aim to find an
exact correspondence at the level of
off-mass-shell fields in coordinate
space. A key ingredient will be our
recent unified description of all
supersymmetric Yang-Mills theories
[3] in terms of the four division
algebras; real (R), complex (C),
quaternion (H) and octonion (O).
The global symmetries that result

from tensoring one (R, C, H, O) theory
with another are then just those of
the so-called Freudenthal magic
square, well-known to mathematicians
[2.4]. But even more interesting is
the Yang-Mills origin of local
gravitational symmetries such as
general coordinate invariance and
local supersymmetry [1].

Professor Jerome Gauntlett
The AdS/CFT correspondence, which
arose out of string theory, is a
powerful theoretical tool to study
strongly coupled quantum field
theories using weakly coupled
gravitational descriptions in higher
spacetime dimensions. In recent
years there has been a concerted
effort to apply these “holographic”
techniques to vexing condensed
matter systems such as high
temperature superconductors and
strange metal phases using, amongst
other things, novel black hole solutions.
In ref 4 we used these techniques to
model the rapid quench of a
superconductor and discovered an
emergent temperature scale in the
superconducting phase below which
the approach to equilibrium is
oscillatory and above which it is not.
We have pioneered the study of
spatially modulated phases and in
ref 3 we investigated the competition
between striped phases and
superconducting phases and in the
process discovered black holes
describing meta-magnetic phases.
In refs 1 and 2 we pioneered the
construction of a class of black hole
solutions that incorporate momentum
dissipation and hence provide more
realistic models of metals. We found
models of coherent metals, with
Drude peaks, incoherent metals
(with some similarity to the strange
metals) and insulators as well as
transition between these states.

In the last year or so I completed
two substantial papers with my
postdoc Dan Bedingham, which
demonstrate two closely related
results for a point particle system:
both quantum-mechanical reflection
off a simple step potential and the
Zeno effect arising from very frequent
position measurements are
suppressedas a result of environmental
decoherence. The classical limit of
these two non-classical effects is
thereby obtained. With four undergraduate project students, I wrote a
paper on how to generate an
exhaustive class of backflow states,
states of positive momenta but
negative current so that the probability
flows backwards, an intriguing nonclassical effect awaiting experimental
confirmation. I also wrote a short
letter offering a new and transparent

In joint work with Neil Lambert, the
possibility of time emerging from a
theory without time was discussed.
We argued that the strong coupling
limit of the maximal super-YangMills theory in 5 Euclidean
dimensions has an emergent time
dimension and gives a description of
the 5+1 dimensional M5-brane
theory, compactified on a timelike
circle. The discussion involved
questions of how to quantise
Euclidean theories without time, and
indeed the meaning of quantum
theory in such systems. Issues of
space-time signature, emergent
dimensions and periodic time were
also addressed.
String theory has duality symmetries,
which allow the construction of nongeometric backgrounds. String
theory on a torus requires dual
coordinates conjugate to winding
number. This leads to physics and
novel geometry in a doubled
spacetime. This is formulated in
double field theory, introduced by

Over the past year I continued to
investigate the cosmology of models
with deformed dispersion relations,
and their relation to dynamical
dimensional reduction, as seen in
many quantum gravity schemes. A
remarkable dual picture was
discovered in [1] dispensing with the
dubious concept of spectral
dimension, replacing it by the
straightforward Hausdorff dimension
o fmomentum space, and shedding
light on they scale-invariance of the
associated cosmological
fluctuations. A better understanding
of how departures from exact scaleinvariance may arise was also
obtained in a couple of papers (e.g.
[2], where a connection with
intermediate inflation was found).
More importantly, a method was
found for introducing deformed
dispersion relations representative
of dimensional reduction without
picking out a preferred frame. This
may prove to be the best set up for
studying these scenarios, with a
minimal number of free parameters.
On different front I continued to

investigate the cosmological
consequences of Cartan gravity,
e.g. regarding signature change
(see [4]). This followed up on earlier
work on torsion and spin cosmology.

I have investigated the cosmological
implications of the Higgs field and other
possible light scalar fields. Together
with my PhD student Laura Bethke and
Daniel Figueroa from University of
Geneva, we showed that in the
presence of a light scalar field, the
gravitational wave background from the
end of inflation in the early universe
would be anisotropic, and that if
observed, these anisotropies could be
used to test and constrain cosmological
theories.2,4 With another PhD student
Stefano Orani, we showed a light
scalar field can arise from a
supersymmetric theory, with interesting
cosmological consequences.3 I am

Our work on AdS/CFT duality
continued along several directions.
We developed an integrabilitybased approach to superstrings in
AdS3 x S3 space discovering that
the corresponding disperstion
relation for elementary magnons has
a novel form different from the one in
the much studied AdS5 x S5 case.
We also investigated integrable
deformations of AdSn x Sn supercoset
models finding new relations between
previously known integrable sigma
models in AdS2 x S2 and AdS3 x S3
cases. We also studied vectorial
AdS/CFT between singlet sector of

My work has focused on understanding
the geometric structures underlying
string theory generalisations of Einstein
gravity, with implications for the AdS/cft

and more generally the symmetry
structure underlying M theory. In
collaboration with two (now former)
PhD students, André Coimbra and
Charles Strickland-Constable, we

dimensional supergravities as
generalised pure Einstein theories
[1,2]. With Strickland-Constable (then
at DESY) and a postdoc at Imperial
College, Kanghoon Lee, we used this
formalism to derive a universal
description of consistent truncations of
supergravities as generalised ScherkSchwarz reductions, giving for the first
time a geometrical understanding of
the remarkable sphere consistent
truncations first discovered in the late
1980s. With Mariana Graña (IPhT,
Saclay), Jan Louis (Hamburg Univ and
DESY) and Ulrich Theis (Hannover) we
analysed the structure of string and
quantum corrections to type II
reductions on SU(3) structure
manifolds, showing that they closely
mirror the correction on conventional
Calabi-Yau manifolds. Finally with
Coimbra, Ruben Minasian (IPhT,
Saclay) and Hagen Triendl (CERN) we
showed how the string corrections to
heterotic sueprgravity could again be
described using the formalism of
generalised geometry. Results from
these last three projects all appeared
as preprints during the year.

Dr Toby Wiseman
During the period 2013-2014 my
research has been focussed on the
gravitational aspects of the AdSCFT correspondence. I have
continued to use numerical methods
to solve the bulk gravitational
Einstein equations in situations of
relevance for dual field theory
physics. In particular I showed how
quench dynamics relevant for
describing holographic
superconductors can be reproduced
[1], and also discussed a new class
Theoretical Physics
of black holes with non-Killing
horizons [2] which is important in
understanding plasma flow in
strongly coupled gauge theory via
holography. I co-authored an invited
review [3] on these and related
topics applying gravitational
methods to study strongly coupled
field theory. I have also developed
new methods to understand the
emergence of black hole physics in
thermal supersymmetric gauge
theory, starting with the work [4],
and this is now an on-going

Research in the Physics Department at Imperial College is a mix of fundamental and end-user-inspired
interdisciplinary science. This profile promotes the primary role of physics in advancing elemental knowledge
and also highlights its crucial role in stimulating economic growth,and in tackling key global issues.
We engage with over 60 external companies through
collaborative research, consultancy, knowledge transfer
and patenting/licencing of our intellectual property. We
also contribute to economic growth through setting up
commercially successful spinout companies.
We collaborate with the commercial sector at all levels
and of course PhD students within the Department benefit from direct industrial sponsorship and EPSRC
CASE awards.
The Department set up an industry club in 2010 in order
to interact on a more regular basis with companies who
are interested to recruit our students and postdocs and
engage with the department on collaborative research

Commercial Interactions, the Blackett Laboratory
Industry Club
The technology developments and commercial activities
within our research groups include the following:
Both the Herschel and Planck teams continue the
development of data reduction and analysis software for
these two missions. For Planck our work is aimed at the
determination of beam shapes and focal plane geometry from actual survey data using either scans across
individual bright sources or through combination of data
on large numbers of fainter sources. This work is crucial
to the science goals of the Planck mission. For Herschel we are coordinating the development of data
reduction and analysis software for the whole of the
SPIRE instrument and have special responsibility for
mapmaking codes through a contract from the European Space Agency which will be used for both the
SPIRE and PACS instruments.
Condensed Matter Theory
The group has a wide-ranging computational and theoretical research portfolio with a strategic focus on materials for structural, electronic and photonic applications,
providing theoretical and computational expertise.
Many projects have direct relevance to the next generation of technologies. Our work on metamaterials has
shown how to create perfect lenses that beat the diffraction limit, how to harvest light efficiently, and how to
make objects invisible. Our work on functional and
structural materials includes studies of radiation
damage in fusion and fission reactors, surfaces and
grain boundaries in perovskites for functional applications, the high-temperature corrosion of Ni- and Febase structural alloys, thermoelectrics for power
generation, capacitors for energy storage, and plasticity
under shock loading.
The Group enjoys working relationships with Accelrys,
Astron, Antenova, Argonne National Laboratory, Baker
Hughes, BP, BAE, Element Six, Materials Design, Placental Analytics, Rolls-Royce, the UK Atomic Energy
Authority, the UK Defence Science and Technology
Laboratory, and the US Air Force Office of Scientific
Research. We hold several patents.
Experimental Solid State Physics
The experimental Solid State Physics Group develops
technologies across a broad range of areas that have
impact on the displays and lighting sector, the information and communication technologies sector, the solar
energy sector, and the health care and security sectors.
Our innovations derive largely from expertise in molecular electronic materials and devices, inorganic semiconductors and devices, nanomagnetism and transition
metal oxides and devices. Programmes span materials
design, synthesis and processing, device fabrication
and optimization and applications assessment. Welldeveloped skills in optical and electrical materials and
device characterization and modelling underpin this
activity. Much of the work in the group proceeds through
collaborative research programmes frequently involving
industrial partners. Leading international companies
that have supported our work include BP Solar, Merck,
DuPont Teijin Films, Sumitomo Chemical Co., Philips
Research Labs., Solvay, Unilever, CDT, Toshiba, BASF,
LG, Solenne B.V., Toyota, and Oxford Instruments. The
group also benefits from collaborations with the NPL at
The group also has a strong record of protecting intellectual property and exploiting it through spinout companies such as QuantaSol and Molecular Vision.
High Energy Physics
The dark matter experimental part of the High Energy
Physics group is dedicated to the development of
advanced particle detectors for 1- 100 keV energies
and associated technology (high precision ultra-high
vacuum technology in copper, partper-billion level gas
purification, charge/light readout technologies, cryogenics). A joint development programme has being undertaken with UK-based ET Enterprises Ltd (formerly
Electron Tubes Ltd) to develop a photomultiplier tube
with ultra-low radioactive background. This work is in
its final stages and promises to deliver the world’s most
radio-pure phototube, which will find world-wide application in large experiments for neutrino detection, dark
matter searches, and neutrinoless double-beta decay.
The underground laboratory at Boulby represents a
symbiotic relationship between industry (CPL mine) and
university research. The gravitational-wave project
drives charge control systems and associated technology (UV light sources, particle guns, satellite instrumentation). For this work the group collaborates with EADS
(Astrium UK, Astrium Germany), Carlo Gavazzi Space
(Italy), ETL, the European Space Agency, SciSys and
Plasma Physics
The Group is engaged in work involving the development and exploitation of high-voltage pulsed power sys-

tems and high-power lasers. Our research using lasers
has led to developments in the field of 'compact'
plasma-based particle accelerators with many potential
applications ranging from advanced light sources to
medical imaging and hadron therapy. We also investigate dusty plasmas, an understanding of which is
important in integrated circuit manufacture and for future
fusion power plant designs.
We collaborate with many companies and organisations
that provide support for our activities in a broad range of
ways including commercial contracts, knowledge transfer secondments, PhD support and through joint grant
awards. These include UKAEA Culham, the Rutherford
Appleton Laboratory, AWE Aldermaston plc, Sandia
National Laboratory, the Laboratory for Laser Energetics
(University of Rochester), the Institute of Laser Engineering (University of Osaka), the US Naval Research
Laboratory and the Lawrence Livermore National Labo-
ratory. We also host the Centre for Inertial Fusion Studies (CIFS) and the Institute of Shock Physics (ISP)
which has substantial links with commercial and industrial organisations, include QinetiQ, THALES and BAE
as well as its major sponsor, AWE. These involve investigations of high-speed impacts e.g. on electronic components, high strain-rate loading of engineering and
biological materials and the development of robust predictive capabilities for systems under extremes of strain
and pressure.
Laser Consortium
Our technology is associated with developing high
intensity and ultra short laser pulses. Theoretical
descriptions of the effect of these intense fields have led
to technology that can be used to produce microscopic
optical structures by laser induced modification (through
multiphoton ionisation) of media. The attosecond basic

technology programme promises to open up new fields
of ultra high time resolution measurement in surface science etc. Technology recently developed as part of this
project has been spun out and a second custom system
for hollow fibre pulse compression to generate 10 fs
pulses has been delivered to RAL under contract. A
broadband phase shaper for high intensity laser pulses
is also in the process of being patented. Plasmas produced by interaction of short pulse lasers with sub
wavelength clusters and micronscale objects are a
promising source for x-ray generation at lithographically
important wave-lengths. They also produce high energy
density plasmas of interest for the testing of numerical
codes. Blast waves in extended cluster media can be
used to model astrophysical and other strongly driven
systems and produce high quality data useful in the
benchmarking of complex radiation hydrocodes. We
have an active collaboration with AWE including funding, personnel exchange and equipment loan.
Quantum Optics and Laser Science
The Group applies cutting edge laser technology, quantum-enhanced technology and detailed numerical modeling to a broad range of measurement and control
problems in information processing, metrology, sensing
and basic physics research. The Centre for Cold Matter
has an ongoing collaboration with the K. J. Lesker company investigating transparent conductive films for polymers. There are also links with PG Technology
(Precision machining company) on design of molecular
decelerators, and with Shimadzu Research Laboratories
(Europe) on the development of novel THz detectors
which has recently resulted in a joint patent.
There are ongoing collaborations with the National
Physical Laboratory (NPL) on ion trapping and the
development of ultra-stable lasers. This has included
supervision of students funded by the NPL who carry
out most of their experimental work there, but who are
registered as students at Imperial College. The Quantum Information Theory sub group has links with a
number of companies including Toshiba and NTT.
In the Photonics group, most of our projects are interdisciplinary and we work closely with industry. Direct support for research into high throughput and
multidimensional fluorescence imaging, particularly fluorescence lifetime imaging (FLIM) has come from Perkin
Elmer Life and Analytical Sciences (UK) Ltd and GE
Healthcare. ‘In kind’ support has come from
AstraZeneca UK Ltd, GlaxoSmithKline R&D, Kentech
Instruments Ltd, Leica Microsystems (UK) Ltd, Olympus
Optical Co UK Ltd. We also have a founding interest in
Aurox Ltd, a spin-out from Oxford University, manufacturing optical microscopy equipment. Our fibre laser programme addresses wavelength and pulse length
versatile, all-fibre configurations primarily deploying
MOPFA (Master Oscillator Power Fibre Amplifier) technology including development of versatile compact seed
sources, to generate high average power, spectrally
bright single mode sources. The fibre laser work has
long-standing collaboration and support from the IPG
Group of Companies. Direct support in the area of high
power diode-pumped solid-state lasers and nonlinear
optics has come from the Electro-Magnetic Remote
Sensing (EMRS) Defence Technology Centre, established by the UK Ministry of Defence and run by an
industrial consortium of SELEX Sensors and Airborne
Systems, Thales Defence, Roke Manor Research and
Filtronic. This involves novel adaptive sensors and laser
sources for enhancing signal and information retrieval in
complex remote sensing scenarios. Pilkington Optronics
(now Thales) have supported CASE awards and ‘in
kind’ support has come from Shell Research Labs,
Spectra-Physics and Spectron Laser Systems. The
European Space Agency is sponsoring the development
of new high efficiency tunable lasers for next generation satellite-based remote sensing for atmospheric and
earth science addressing climate change, weather prediction and monitoring the health of the Earth’s biosystem.

Space and Atmospheric Physics
The group has a long history of leading magnetometer
instruments for space research. Our continued collaboration with Ultra Electronics Ltd has resulted in a new
fluxgate design which at 100g is half the mass of any
sensor we have previously flow in space. We completed
a collaboration with EADS Astrium, MSSL (UCL) and
SciSys Ltd to validate new data-handling architectures
for future small satellites where processing power and
resources will need to be shared amongst many users.
We have also completed a first stage of testing new,
commercially available, solid state magnetoresistive
sensors, with promising results.
As part of an EU Marie Curie Research Training Network GLADNET we are also studying the characteristics
of Glow Discharges, used as an analytical method in
industrial applications for example in quality testing of
thin coatings.
The group is strongly engaged with the Climate knowledge Innovation Community (KIC) and is developing the
next generation catastrophe model software for the
insurance sector.
Theoretical Physics
The dominant part of the Group's activities lie in studying theories of the fundamental nature of the universe
and associated commercial applications arise in the
very long term. However, there are some subsidiary
consultancy activities.
Tim Evans is a consultant with Digital Science who produce software to
collate and analyse information for academics and academic institutions, for instance Digital Science produces
Symplectic's Elements software which manages the
publications of academics at Imperial College. He is
also a Scientific Advisor to NewsfFlo who produce software to collate and analyse
information from News outlets for academic institutions.
Jerome Gauntlett is a Scientific Advisor for the Arts Club
in Mayfair and he was the Theoretical Physics consultant for the film the Theory of Everything.

Industry Club
In 2010 the department set up the Industry Club, with
the aim to enhance the good working relationships that
exist between the Imperial College Physics Department
and a number of companies and to develop such relationships with new partners. The department set about
creating two departmental wide events per year inviting
all Industry club members. The PGR Research Symposium event which is held in June each year, is a show
casing event where all second year PhD students present posters and all third year PhD students give talks.
Industry club members are involved in choosing poster
prize winners. The second major event of the year is the
industry club recruitment event, which is a more traditional career fair. Both events are well attended.
Laboratory, Oxford Instruments, IPG Photonics, Qioptiq,
RBS, Renishaw, TTP, Toshiba, Winton Capital.
Bespoke recruitment events were held for Winton Capital, Renishaw and Electronic Arts.
In 2014, the industry club co-sponsored our international undergraduate summer research exchange programme (i-UROP) at Massachusetts Institute of
Technology, University of British Columbia,and Seoul
National University creating the opportunity for seven of
our third year Physics undergraduates to enjoy a state
of the art research experience.
The industry club also sponsors a PhD thesis prize and
two of our club members AWE and Winton Capital also
sponsor their own named post graduate thesis prize.

Blackett Laboratory Alumni Events 2013-14
Early in 2014, the department was approached by the
1974 undergraduate cohort, a subset of which keeps in
regular contact with each other. The group got in touch
with Linda Jones, now Departmental Administrator,
asking whether a function could be held for them over
the Imperial Festival in May. The request resulted in the
Department hosting a social event for over 100 alumni
within (the very fondly remembered) Blackett level 8
common room. Linda toured many of the alumni to visit
the level1 main lecture theatre and other familiar
Inspired by the success of this event, and recognising
the need to provide Physics focused alumni visits, the
department contacted the College Alumni office to ask
them to help organise the first formal Departmental
alumni function. In September 2014, over 120 alumni
attended an exclusive Physics event to hear Professor
Sir Tom Kibble talk about his role in the prediction of the
Higgs Boson. the elusive particle whose existence was
finally confirmed at CERN in 2012. Alumni were offered
tea and cake in the Blackett Laboratory foyer (a trip
down memory lane for many) followed by a champagne
reception in the common room and the 8th floor roof terrace overlooking the West London skyline and the
Royal Albert Hall. The appeal of such a prestigious
speaker was apparent as the event attracted a huge
range of alumni from recent graduates through to those
who were taught by Professor Kibble himself.
Friends of Imperial Theoretical Physics
In 2013 the Theoretical Phyiscs Group at Imperial College initiated a new association called "Friends of Imperial Theoretical Physics" or FITP for short. The purpose
of FITP is to host periodic popular talks at South Kensington campus allowing members to keep abreast of the
exciting research that is currently going on in the Group
and in theoretical physics more generally.
Department of Physics Review 2013 -14
Blackett Laboratory Alumni Events 2013-14
In 2013 FITP hosted a Symposium celebrating Tom
Kibble's 80th Birthday concluding with a keynote talk by
Nobel Laureate Steven Weinberg to a packed audience
of over 700 people in the Great Hall.
In 2014 FITP organised a talk titled "The World in
Eleven Dimensions" by Professor Michael Duff FRS, the
Abdus Salam Professor of Theoretical Physics.

interesting and exciting out to the next generation.

A Grand Day Out!
Imperial Festival 2014, the dates went straight into our
calendar when we received our email from
the Friends. This was our third Festival, and
it didn’t disappoint, the event seems to be
going from strength to strength.
First of all, a visit to the Alumni base in the
Senior Common Room. Always a cheerful
welcome with a good cup of coffee and biscuits to get us going. Everyone is keen to
chat and within minutes we had been
exchanging words with an alumnus of 1958
Elec Eng who was visiting with a fellow student and a recent alumnus of 2013 Computer Science who had climbing the Queen’s
Tower firmly on her agenda.
Next the big marquee. So much to see, so
much to learn about, so much to try. Knowledgeable students keen to share their enthusiasm; explaining, demonstrating and
inspiring the Festival visitors. Great to see so
many children who had come along with
their families having such a good time controlling skiing
penguins by nodding their head, whizzing cars down
tracks to simulate DNA, looking at tape worms in jars,
ugh! My own favourites included the 3D printer attached
to the scanning fluid pipette which generated amazing
models such as of the eye of a fly. Also the enthusiastic
epigenetics student whose patience whilst trying to
explain to two physicists what it was all about was
Lectures to go to, workshops to try out, Jezebel and Bo
to visit, the day sped by but we were keeping an eye on
the time as we had an important date at 4:30pm. The
Physics Department had invited alumni for a nostalgic
visit to the department- and they did it in style. We met
in the Senior Common Room on level 8, scene of our
post finals party so many years ago. We were warmly
welcomed by organiser Linda Jones, the Physics
Department Operations Manager, and Professor Lesley
Cohen, Director of External Liaison. Wine and a superb
buffet ensured that people relaxed, mixed, reminisced
and generally had a really good time.
Thank you for a day to remember for alumni like us. It is
also great to see that IC is doing such an excellent job in

Juno Transparency and Opportunity Committee
The Juno Transparency and
Opportunity Committee meets
monthly throughout the year. The
business of the meetings is driven
by (i) the evaluation of progress on
the action plan from the last AthenaSWAN application, and (ii) new and
on-going initiatives related to wider
issues, such as the gender and the
racial imbalance among physics
students. Information about the
committee’s activities, including the
minutes, are disseminated to the
department through the committee
website, which is accessible through
the departmental website.
The activities of the committee are
often driven by an individual
member, which is then supported by
the committee as a whole through
advice and concrete action. During
the previous year, the main output of
the committee is as follows:
1. Following a meeting between
several members of the committee
and Elizabeth Truss MP (at the time
Parliamentary Under-Secretary of
State for Education and Childcare)
at the Department for Education
(DoE) an invitation was issued and
accepted for her to visit Imperial in
2014. That visit happened on May
14, 2014, when the Under-Secretary
emphasised the need for better math
and science teaching to encourage
more pupils to take up STEM
subjects after the age of 16,
particularly girls and those from less
affluent backgrounds. This was also
a central theme during the visit to
the DoE.
