# Theory of Condensed Matter

Theoretical Condensed Matter physics is about building models of physical processes, often driven by experimental data, generalising the solutions of those models to make experimental predictions, and transferring the concepts gained into other areas of research. Theory plays an important role in understanding known phenomena and in predicting new ones.

With over seventy members, the TCM Group is one of the largest research Groups in the Cavendish Laboratory, and the largest university Condensed Matter Theory group in the country. Able to trace its history back for over sixty years, it has been home to many leading theoreticians.

Starting at the first principles microscopic level - with the Schrödinger equation - many properties of materials can now be calculated with a high degree of accuracy. We work on refining and developing new calculational tools and applying them to problems in physics, chemistry, materials science and biology.

Solids often show unusual collective behaviour resulting from cooperative quantum or classical phenomena. For this type of physics a more model-based approach is appropriate, and we are using such methods to attack problems in magnetism, superconductivity, nonlinear optics, mesoscopic systems, polymers, and colloids.

Collective behaviour comes even more to the fore in systems on a larger scale. As examples, we work on self-organising structures in "soft" condensed matter systems, non-linear dynamics of interacting systems, the observer in quantum mechanics, and models of biophysical processes, from the molecular scale up to neural systems.

We are pleased that Nigel Cooper has been selected as a 2017 Simons Investigator in Physics, an award worth over $½m with Nigel being this year's only UK recipient. The citation mentions Nigel's work on optical lattices for cold atoms that provide controllable laboratories for studying interacting particles in gauge fields, and his work on the topological Kondo effect and on quantum oscillations in topological insulators.
