Theoretical and computational physics

We study how components of complex systems interact with each other, and how this leads to unusual behaviour and novel applications.

Simulation of angle-resolved photoemission spectrum of twisted bilayer graphene, a novel material in which a twist between two atomic layers tunes the importance of many-body effects

Our research in theoretical and computational physics involves a wide range of systems, which typically consist of many interacting components, such as molecules, 电子, or living organisms.

Newton's laws of motion are often successful in describing the dynamics of systems of atoms and molecules, and Schrodinger's equation can be used to understand much of materials physics. But looking at the equations themselves gives no hint of the important physical phenomena like crystal formation or the operation of solar cells contained within their solution. 类似的, even simple interactions between living organisms can result in unexpected spatial or social organisation.

These examples show that simple equations and simple systems can support complex emergent behaviour. 幸运的是, mathematical and computational tools from theoretical physics are ideal for understanding the complex phenomena that are observed in nature.

In the Theoretical and Computational 物理 group, we exploit methods like Monte Carlo simulation, network analysis and density functional theory. We use them to investigate:

  • Light propagation in photonic crystal fibres (大卫的鸟)
  • Electronic structure and dynamics (Simon Crampin)
  • Astrophysics of gamma-ray bursts and cosmic explosions (Hendrik van Eerten)
  • Non-linear and quantum nano-photonics, non-linear optics of 2D materials (Andriy Gorbach)
  • Biological networks and collective behaviour (迪克·詹姆斯)
  • Two-dimensional materials and van der Waals heterostructures (Marcin Mucha-Kruczynski)
  • Nonlinear waves in photonics and condensed matter (Dmitry Skryabin)
  • Soft matter, topological states, mechanics, and metamaterials (Anton Souslov)
  • Protoplanetary systems, formation of accretion disks and variational methods for non-Hamiltonian systems (大卫曾)
  • Perovskites and organic solar cells and organic optoelectronic devices (Alison Walker)


There are opportunities for postgraduate research throughout our group. Interested students can either contact academic staff directly or look at their proposed PhD projects posted on

The group environment

The Theoretical and computational physics research group carries out research in diverse fields and in collaboration with many other groups across the world.

For numerical calculations, we make use of dedicated group computing servers as well as the university's high performance kilonode computing cluster which provides a powerful resource for tackling computationally intensive problems.

We have regular seminars on research within the group and frequent visits from external speakers. By meeting together in this way, we are able to share new methods and identify novel problems for future study.
