Welcome to the Theoretical Physics Research Group at the University of Birmingham, UK! We are a part of the School of Physics and Astronomy. Our group’s research interests span a diverse spectrum of condensed matter, ultracold-atom, and nonlinear-optical systems on length scales from the microscopic through mesoscopic to the macroscopic. Our research has common threads of correlation, disorder and topology encompassing such topics as many-body localization, topological phases, time-crystals, and quantum critical phenomena.
