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.
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.

The TCM 60th photo is now available online to view and order online.
TCM-CASTEP AFC scraped a 15-5 defeat to the Finance Division in the Cavendish Purple Shin Football tournament.
To mark 60 years of SST/TCM, we held a half-day symposium and a celebratory dinner.
