Theoretical Physics

Theoretical Physics underpins much of the School's research. Our work encompasses diverse problems, from understanding fundamental features of quantum mechanics to unravelling many-body, topological and statistical effects in both quantum and classical regimes within solids, complex liquids and optics. We have considerable expertise in devising applications of emerging quantum technologies, using high-performance computing and modelling quantum materials and soft matter. We specialise in the following six research areas: 

• Electronic structure of novel quantum materials

Investigating novel materials ranging from unconventional superconductors, topological insulators and frustrated magnets, with the aim of understanding the exotic ordering of their constituent spins, charges and orbitals.

• High-performance scientific computing

Developing algorithms and efficient codes for solving complex physics problems in diverse areas exploiting state-of-the-art scientific computing resources.

• Non-equilibrium many-body physics

Studying non-equilibrium phenomena in many-body systems, ranging from ultra-cold atoms to strongly correlated electron materials, with a focus on understanding the nature of entanglement and correlations in their quantum states.

• Quantum information and foundations

Researching fundamental aspects of quantum physics by uncovering seemingly paradoxical new quantum effects that together point to a deeper understanding of its foundations.

• Statistical, liquid state and soft matter physics

Developing theories for bulk phases and structure at interfaces for complex fluids such as colloids and knotted macromolecules by applying Monte Carlo methods and abstract topological concepts.

• Wave geometry and optical field theory

Focusing on the phenomena lurking between the domains of classical and quantum physics to expose the beautiful unifying mathematical ideas of asymptotics governing the behaviour of light, fluids and atoms.
