We are a Theoretical Physics group at UC Berkeley specializing in the study of Condensed Matter Physics. We seek to understand properties of matter such as superconductivity and magnetism starting from fundamental physical laws like quantum mechanics. Historically, this has led to a deeper understanding of interacting quantum systems of very many particles as well as applications like the transistor, magnetic memories and magnetic resonance imaging .
This wordle gives you a picture of our current interests which includes topological phases with strong interactions, unconventional quantum critical points and and three dimensional zero-gap semiconductors (i.e. Weyl and Dirac semimetals). We explore both the fundamental theory of such states, as well as their experimental signatures.
We use a variety of theoretical tools, e.g. quantum field theory, but our research is primarily guided by interesting physical problems and ideas rather than techniques. We are happy to pick up new tools if they suite the problem at hand - for example we recently exploited concepts from quantum information theory to sharpen our understanding of topological phases. We also work closely with experimental groups that study interesting states of matter in solids and ultracold atomic systems.
