This wordle gives you a picture of some of our current interests which include:
(i) Theory of Moire materials including magic angle graphene.
(ii) Unconventional quantum critical points, dualities & topological phases with strong interactions,
(iii) Topological Band Theory including Weyl semimetals.
(iv) Quantum coherence in non-equilibrium many body systems.
We are a Theoretical Physics group specializing in the study of Condensed Matter Physics. We seek to understand phenomena such as superconductivity and magnetism starting from quantum mechanics and other basic physical principles. Historically, this has led both to a deeper understanding of quantum systems of very many particles as well as new devices and applications like the transistor, magnetic memories and magnetic resonance imaging.
