| Assoc Prof Andrew James Kricker | Prof. Kricker's most significant research interest lies in the mathematical ramifications of current developments in mathematical and theoretical physics. To be precise, he is interested in the ramifications of certain developments in quantum field theory and quantum gravity in the fields of topology, algebra, and combinatorics. Prof. Kricker's particular speciality is in so-called "quantum topological invariants". These are invariants of knots, 3-manifolds, and various other low-dimensional topological structures, that arise from Topological Quantum Field Theories. More generally, he has a considerable general interest in the fields that surround this topic: knot theory, the theory of low-dimensional manifolds, Lie algebras, Hopf algebras, representation theory, homological algebra, algebraic combinatorics, and so on. |

The design and realisation of new devices based on the fundamental laws of quantum mechanics are always at the centre of my interests. My continuous interactive dialog with industrial partners has driven these investigations towards the matching of fundamental research with long-term technological needs.

One such behavior is the phenomenon of "coherent perfect absorption"—the complete absorption of light via waveform tuning—a concept that I helped to develop.

| Prof Christos Panagopoulos | Driven primarily by innovations in materials science and engineering, his research focuses on condensed matter systems with spontaneous tendencies toward complex electronic pattern formation.

Panagopoulos develops an international coordinated effort on the science and applications of emergent complex phases in modern materials. Understanding and controlling these spontaneous tendencies will enable the design and development of highly sensitive micro- and nano-scale devices where we tune electronic matter to the widest possible range, starting from an insulator to a high temperature superconductor. |

| Asst Prof Gu Mile | One of the most remarkable facts about the universe is that it can be simulated on a computer. No matter what systems we study, whether it is the dynamics of planets or that of fluids, the rise of fall of tides or stock markets, they all can be simulated by a computer. This fact fascinates me.
After all, a computer is typically built out of silicon; it runs via the electro-magnetic force. What a priori reason would it allow us to understand the motion of planets governed by gravity, fundamental particles govern by the strong and weak force? This universality is, when you think about, rather remarkable. Somehow, everything we know around us, can be reduced to the processing of information.
My research interests are motivated by this remarkable observation. Can we find interdisciplinary laws that span multiple disciplines through the understanding of how nature fundamentally processes information? Some current directions:
On outset, Quantum and complexity science appears to be very different. The former details with objects at the atomic scale – atoms, electrons and photons. The latter, on the other hand, is typically associated with macroscopic systems is many interacting components – the weather, traffic, stock markets.
Yet the two science, in fact, an intimately linked; both are bring transformed by the study of information. In quantum science, new information theoretic techniques have allowed the `second quantum revolution’; heralding exciting new quantum technologies such as quantum cryptography and quantum computation. Meanwhile, in complexity science, researchers’ new ways of understanding just how massive systems interact with each other by seeing how they transform and process bits of data.
My interest is to unite these two fields – by forging new connections. Can quantum computation lead to new ways of understanding complex systems? Can the use of methods of complexity science help us understand how quantum computer’s get their power and bring forth new quantum technologies?

What Makes Quantum Computers Powerful?
What are the resources behind Quantum Advantage? Quantum computers are heralded to do many things that classical computers cannot, but what resource powers this advantage? For a long time, people thought that the main culprit is quantum entanglement – the unique quantum phenomena where the realities of two spatially separated particles are closely linked. Yet we now see that this may not be the full story. DQC1, for example, seems to allow us to compute the normalized trace of an exponentially large matrix in efficient time – and yet contain negligible entanglement. Meanwhile quantum illumination allows the better detection of faint particles far away in regimes so noisy that entanglement cannot survive. What other resources are associated with improved quantum advantage? We are interested in this question both for practical and foundational concerns. On the one hand, it can lead to noise resilient quantum technologies; on the other it may tell us fundamentally what is quantum. |

| Asst Prof Liew Chi Hin Timothy | Spin Dynamics of Excitonic Systems :
Excitons are bound hydrogen-like states of electrons and holes, typically appearing in semiconductor quantum wells. Their electric dipole moment allows them to couple to light, particularly in semiconductor microcavities, and if this coupling is strong enough it can lead to hybrid states of excitons and light known as exciton-polaritons. Being hybrid states, exciton-polaritons inherit a mix of electronic and optical properties, including strong nonlinearities, sensitivity to electric/magnetic fields, long coherence times, fast picosecond scale dynamics. Theoretically, excitons and exciton-polaritons are also interesting for their rich spin dynamics, which gives rise to the optical spin Hall effect, spin-to-orbital angular momentum conversion; and spinor vortex dynamics.
Optical Circuits :
The nonlinearity of exciton-polaritons implies their application as optical circuit elements. While exciton-polariton systems are highly lossy, they admit a mechanism of signal propagation that mimics the signal propagation of biological neurons where losses are fully compensated by amplification. Recently a complete theoretical framework of polariton based circuits has been developed , accounting fully for disorder and finite lifetime. Mechanisms of hybrid electro-optic circuits can be based on incoherently excited polariton transistors or alternative mechanisms of bistability.
Quantum Optics in Weakly Nonlinear Systems :
To generate quantum effects from an optical system one typically requires nonlinearity stronger than the system decay rate. For example, the well known photon blockade effect requires the interaction energy between two photons to exceed the linewidth. Unfortunately, most photonic systems (e.g., microcavities or photonic crystals) have short photon lifetimes. Recent research moves to circumvent this problem by making use of quantum interferences or mechanisms of amplifying a weak nonlinearity.
Bosonic Quantum Cascade Lasers :
A variety of semiconductor nanophotonic systems have been considered for the emission of terahertz radiation, where one typically aims to convert an optical photon into a terahertz photon. While terahertz sources have several practical applications, this process is highly inefficient as the terahertz photon carries only a small fraction of the initial energy. To overcome this problem, the concept of a bosonic quantum cascade laser has been introduced , making use of multiple terahertz emitting transitions in an exciton trap. Unlike fermionic quantum cascade lasers, the efficiency is greatly increased by bosonic final state stimulation (achieving quantum efficiency above unity) while the system size is on the micron scale.
Topological Photonic/Exciton Systems :
The field of topology has proven how macroscopic properties of physical systems can result in exotic features at the boundaries between topologically distinct materials. Following earlier ideas from electronic topological insulators and photonics, the theory of topological polaritons and topological indirect excitons was recently introduce. In these systems, density currents propagating in chiral edge states are protected from scattering with disorder, which is a clear advantage for exciton based optical circuits.
Optical Neural Networks :
Neural networks exploit massive interconnectivity to become highly efficient at certain tasks, such as classification, and pattern recognition. While biological neurons may operate individually on millisecond time scales, their simultaneous connection to several thousands of other neurons allows a parallelization of tasks far beyond the capabilities of complementary metal-oxide-semiconductor logic. Naturally, this observation has motivated research into optical neural networks.

| Assoc Prof Loh Zhi Heng | The central theme of our experimental research program is the study of coherent electron and nuclear dynamics in molecules and nanomaterials. Coherent electron motion and the ensuing quantum dynamics set forth by either optical excitation or nonresonant strong-field ionization with few-cycle laser pulses will be probed with attosecond to femtosecond time resolution. This proposed work builds upon my previous work, in which coherent electron motion in Kr+ ions that accompanies the formation of a spin-orbit wave packet is observed (Nature, 2010).
The main experimental techniques that are employed include attosecond time-resolved core-level transient absorption and transient photoelectron spectroscopies, in which soft x-ray pulses produced in a tabletop setup by high-order harmonic generation are used as probe. These soft x-ray studies are complimented with optical pump-probe measurements employing few-cycle (~5 fs) laser pulses. The ultimate goal of our studies is to exploit quantum coherences to enhance the performance of nanoelectronics and artificial light harvesting systems. |

| Asst Prof Marco Battiato | In the past, Marco Battiato developed the model of superdiffusive spin transport as a mechanism of the ultrafast demagnetisation, prediction which was experimentally confirmed. He has worked since then on several topics that stemmed from the discovery of the ultrafast spin transport: 1) ultrafast spin injection, 2) triggering of ultrafast demagnetisation via injection of excited unpolarised carriers, 3) ultrafast increase of the magnetisation, 4) generation of THz emission via injection of ultrashort spin current pulses in high SO coupling materials, and 5) injection of ultrashort spin current pulses from ferromagnetic metals into semiconductors.
He is currently interested in a wide range of phenomena that arise from the complex interplay of strongly out-of-equilibrium electronic populations in real band-structures, out-of-equilibrium transport in multilayers, and formation of THz electromagnetic fields. He is developing a massively parallel solver for the full Boltzmann-Maxwell system for real space transport in ab-initio band-structures, using the most general (without close to equilibrium approximations) expression of the collision operator for strongly out-of-equilibrium thermalisation dynamics.
He is applying the method to:
- Thermalisation of laser excited carriers in topological insulators;
- Ultrafast spin transport in metallic multilayers and metal-semiconductor junctions;
- THz emission after laser excitation of multilayers;
- Ultrafast dynamics triggered by THz excitation.
Finally one of his main goals is the construction of all the building blocks of ultrafast THz spintronics using the sub-picosecond spin current pulses as vector of information. |
| Asst Prof Marcos | His research interests include small scale fluid dynamics, microfluidics, swimming in non-Newtonian fluids, and bio-locomotion. |
| Prof Maria-Elisabeth Michel-Beyerle | We apply modern tools in ultrafast laser spectroscopy and surface imaging to a broad range of problems in condensed phase structure and dynamics. Most of the problems relate to biopolymers. These have the beauty of touching on basic questions in the field of molecular photophysics, while aiming at insights urgently needed for design and optimization of devices in biotechnology and solar energy conversion.
Electrochemical control of topology of immobilized biosystems. This research addresses DNA-, protein-, and hybrid DNA-protein structures which are immo-bilized at macroscopic surfaces or at nanoparticles. The focus is on the dynamics of electronically excited states in tailored architectures reporting on processes as excitation energy transfer, electron transfer, and proton transfer as well as on disorder phenomena, conforma-tional fluctuations, and self-organisation. These object-tives are pursued in a joint effort focussing on one hand on the design and synthesis of functional DNA, protein and hybrid structures and, on the other, on a variety of experimental techniques involving the measurement of excited state lifetimes and the identification of deactivation pathways in the femtosecond to the subnanosecond range. When performed under confocal conditions, fluorescence lifetime profiles yield temporal and spatial information with a resolution of single domains and possibly single molecules. A novel feature of our approach is the control of disorder-order transitions by the fluorescence lifetime profile of single domains in an electrochemical potential.
Structure-based dynamics in DNA and proteins. Our interest is in the dynamics of electronically excited states, their intramolecular and intermolecular interactions including charge transfer and conformational relaxation. In this spirit we have recently extended femtosecond time-resolved studies to more complex and most relevant DNA structures as quadruplexes and also to nucleosomes with focus on in situ photorepair of light-induced defects (thymine cyclobutane dimers). The role of conformational flexibility in charge transfer processes, one of the still open questions in the field of charge transport in DNA, is studied using DNA double strands which carry changes in the sugar-phosphate backbone.
In the area of proteins, apart from the effect of non-canonical amino acids on the excited state dynamics in GFP, the Green Fluorescent Protein, we study at present how the lifetime of a single excited tryptophan responds to the presence of ATP at the periphery of a specific subunit of the molecular motor enzyme ATPase.
Development of optimized molecular/semiconductor hybrid systems for solar cells. Conversion of solar radiation to electrical energy can be performed by excitation of a dye or other light-absorbing material (preferentially quantum dots) followed by a transfer of the electron into a semiconductor and from there into another part of the circuit, thus providing an efficient source of electricity. A principal problem of such devices is the back reaction, in which the electron returns to the electron deficient injector instead of contributing to an electric current. New activities in our group are dedicated to the development and examination of novel electron injecting systems which are expected to show a drastically reduced back reaction, thus enhancing the efficiency of the solar conversion device. |

| Assoc Prof Massimo Pica Ciamarra | We are interested in understanding the physics of disordered many-particle systems via statistical mechanics tools and numerical simulations, which is arguably one of the most pressing needs in material science.

The main difficulty is the developing of a theoretical framework connecting the macroscopic and the microscopic scales in the presence of disorder. Some topics of specific interest are:
1. glass transition
2. suspensions of soft deformable particles, e.g. microgels
3. liquid with density anomalies

| Asst Prof Ni Ran | The concept of "soft matter" was first introduced by Pierre-Gilles de Gennes in his Nobel lecture in 1991. Essentially, soft matter is a subfield of condensed matter comprising a variety of physical systems that are deformed or structurally altered by thermal or mechanical stress of the magnitude of thermal fluctuations. Because of their responsivity with respect to perturbations, e.g. thermal fluctuations, mechanical deformation, external fields, etc., soft matter have shown great promise as the next generation “smart materials”.
In our group, we use computer simulation as a tool to study and predict the structural properties and dynamic behaviour of soft matter systems in and out of equilibrium to direct the experimental fabrication of functional materials. In particular, we are interested in the self-assembly of colloidal and (bio) polymer systems and work synergically with experimentalists to design new functional materials with application in photonic devices, bio-sensor, bio-materials, etc. Presently, we are interested in the projects below:
1. Dynamic assembly of active matter
2. Glass transition of anisotropic colloids
3. Hierarchical self-assembly of anisotropic colloids
4. Self-assembly of fibril-forming polypeptides |

| Assoc Prof Pinaki Sengupta | My research interests lie in exploring the physics of strongly correlated many body systems combining analytical and computational approaches, focusing on novel quantum phases and quantum phase transitions that arise from the interplay between competing interactions, lattice geometries and external potentials like applied magnetic field. The search for such exotic phases is driven by fundamental and technological motivations. The technological interest results from the possibility of novel functionalities – such as colossal magnetoresistance and high temperature superconductivity – associated with these new states of matter. The theoretical motivation lies in understanding the nature of fundamental interactions in matter. Working closely with several experimental groups, I use analytical methods supplemented by large scale computer simulations to develop theoretical frameworks (based on appropriate microscopic models of the relevant materials) to explain the many unique experimental observations and provide guidelines for future experiments in different strongly correlated systems including quantum magnets and ultracold atoms trapped in optical lattices. Some representative problems that I have worked on in the recent past are:
1. Supersolid: The supersolid is a novel phase of matter that has simultaneous solid and superfluid character. Although first postulated more than 50 years ago, this phase has never been observed in nature despite intense experimental efforts. I showed for the first time the conditions necessary for realizing such a phase in trapped ultracold atoms in optical lattices. Subsequently, I extended the idea of supersolid phase to quantum magnets and proposed the spin supersolid phase, an idea that has gained widespread recognition in the Condensed Matter Physics community.
2. Quantum magnetism at high magnetic fields: The rapid advance in material synthesis has produced a wide variety of spin compounds with different moments, interactions and geometries. The interplay between competing interactions, coupled with strong magnetic fields results in several novel quantum phases. I work with several experimental groups at the National High Magnetic Field Laboratory (USA) as well as at Oxford and Cambridge Universities (UK) to understand the unique experimental observations in many such compounds including formation of magnetic crystals and Bose Einstein Condensation of magnons.
3. Ultracold atoms in optical lattices: A rapidly emerging field of research lies at the interface of Atomic and Condensed Matter Physics. Magneto-optic trapping and evaporative cooling of atoms has opened a new frontier in the study of strongly correlated systems. I have investigated the novel superfluid to insulator transition in these systems, the interplay between interacting Bosons and Fermions, and the formation of quantum glassy phases in the presence of disorder.
4. Control of quantum systems: I have developed a scheme to designing soft scalable pulses for the coherent control of interacting quantum systems (qubits). Such pulses have important applications in the fields of solid state Nuclear magnetic Resonance, quantum information processing (including quantum computation) and optical (laser) probes for biomedical applications.
5. Theoretical biology: Cholesterol plays an important role in the stability of lipid membranes. Experiment shows that at certain concentrations of cholesterol, the membrane acquires extra stability. Using a simple model, I explained the origin of this enhanced stability. |

| Prof Simon Redfern | Professor Redfern's work explores how minerals control and reflect Earth processes and he has worked in collaboration with a wide variety of Earth and environmental scientists, from climate scientists to volcanologists to palaeontologist to seismologists and even exoplanetary “geo”scientists. In all cases he is interested in how insights into nanometre scale features provide understanding of global processes. His work has extended to using insights from nature to develop new materials in the context of materials design and engineering.
His research interests focus on the physical and chemical properties of minerals and associated fluids in planetary interiors. He uses experimental and computational methods to understand the role of minerals in Earth and planetary processes at extreme pressures and temperatures. I has published more than 270 peer-reviewed papers in the scientific literature (H-index 46 [ISI], 54 [Google Scholar]), in internationally leading journals including Nature, Science, Physical Review Letters, Advanced Materials, Earth and Planetary Sciences Letters, JACS, Applied Physics Letters, and GRL. His research is highly inter-disciplinary and he has as many papers in the materials physics/chemistry literature as in geosciences.
Professor Redfern pioneered the development of combined high-pressure high-temperature methods for the study of materials and minerals by neutron scattering and was at the vanguard of researchers using neutron methods in Earth and planetary sciences, and built new facilities at Rutherford Appleton Laboratory (UK) for the wider user community, including the first high-temperature high-pressure Paris-Edinburgh Cell for deployment at neutron sources, now used worldwide. From 2003 to 2006 I was Chair of the working group that designed and implemented the Extreme Conditions Beam Line (I15) of the Diamond Light Source synchrotron.
He has edited several thematic sets of papers resulting from international scientific meetings that he convened, including a volume of Reviews in Mineralogy (Mineralogical Society of America) on "Transformation Processes in Minerals", his primary area of expertise. I have held several competitive UK research grants (total funding of more than £25m) and has led collaborations with a strong group of postdoctoral fellows and research students. He has supervised over 30 PhD students in Cambridge, and acted as postdoctoral mentor and advisor to more than 20 postdoctoral researchers, most of whom have gone on to permanent academic, business or governmental science positions. |
| Prof Sum Tze Chien | My research focuses on investigating light matter interactions; energy and charge transfer mechanisms; and probing carrier and quasi-particle dynamics in a broad range of emergent nanoscale light emitting and light harvesting systems using Femtosecond time-resolved spectroscopy. These can be categorized under two main research themes: (1) light emitters/lasing and (2) photovoltaics. I have also established a 3rd category: (3) Aspirational Areas to explore new ideas and concepts away from my two core research themes. Specifically, I seek to address the following three questions in these systems:
(a) Where did the energy go? That is the interplay of carrier/quasi-particle dynamics between the host energy levels, defect energy levels and the dopant energy levels.
(b) What are the underlying photo-physics and light-matter interactions that give this system its unique characteristics? That is the various processes such as carrier-carrier scattering, carrier-phonon scattering, radiative recombination and auger recombination etc.
(c) How can these properties/technologies be improved for practical applications? That is how the knowledge gained be used for the development of novel optoelectronic devices; nanolasers; and photovoltaic devices.
Today, my group tackles a broad spectrum of research problems in emergent materials (such as halide perovskites, 2D materials etc) ranging from novel photophysics, solar cells, LEDs, lasing, spin phenomena, hot-carrier phenomena and nonlinear properties.
(1) Light Emitters/Lasing: We seek to understand the interplay of carrier/quasi-particle dynamics between the host energy levels, defect energy levels and the dopant energy levels and the factors affecting amplified spontaneous emission or lasing in these II-VI nanostructures such as ZnO nanowires, CdS nanowires and even the mixed dimension CdSe dot/ CdS nanorod heterostructures and organic-inorganic halide perovskites.
(2) Photovoltaics: Ultrafast optical spectroscopy allows us to trace the fate of the carriers and quasi-particles in photovoltaic devices from genesis to the end with timescales spanning over ten orders of magnitude. Correlated with electrical characterization techniques, new insights into the mechanisms of charge generation, transfer, trapping, recombination and transport in novel PV materials can be gained through these studies.
(3) Aspirational Areas: Presently, we live in a highly competitive era of rapid technological changes and shortened innovation cycles, where a keen sense and nimbleness to seek out opportunities is key to sustaining economic growth and our quality of life. These aspirational areas on 2-D Materials, novel nonlinear optical properties and spin phenomena allow us to explore new ideas and concepts apart from our core research. |

Commercial microelectromechanical systems have reached micron scales, and bona fide molecular apparatuses began to emerge setting the stage for upcoming integrated nanoelectromechanics. Dr. Zhao and coworkers systematically investigate carbon-nanotube-based oscillators, bearings and rotators via molecular dynamics simulation in order to establish their optimal operating conditions and to facilitate function-oriented designs. In addition, particular attention is paid to utilization of nanomachinery devices as nanolabs to study energy exchanges among various degrees of freedom, ergodicity on energy surfaces, and equipartition as systems relax, and to test fundamental hypotheses of thermodynamics and statistical mechanics.
The advent of ultrafast femtosecond laser spectroscopy brings about intense research interest in relaxation dynamics of photo-excited states in liquids and solids. Newly-arrived technological capabilities to control femtosecond pulse durations and down-to-one-hertz bandwidth resolutions provide novel probes on vibrational dynamics and excitation relaxation. Dr. Zhao and coworkers formulate time-dependent polaronic wave functions that facilitate microscopic modelling of photo-generated excitation relaxation and realistic computation of various third-order optical response functions, and help to achieve a satisfactory comparison between theory and experiment.
Carbon nanotubes are attractive candidates for a variety of applications thanks to their remarkable physical, chemical, and mechanical properties. Optical absorption and fluorescence spectroscopy measurements have become an important tool for structure-based characterization and DNA-assisted manipulation of carbon nanotubes. Dr. Zhao and coworkers establish visual, intuitive connections between optical absorption line shapes and their underlying nanotube structures, which are scrutinized by more sophisticated semi-empirical and DFT calculations. |
