Research in the Kennett group focuses on problems in quantum condensed matter. Research themes include disordered and out of equilibrium quantum systems, especially those where interactions between particles are important. Lately, we have been focused on disordered, interacting electron systems and cold atoms in optical lattices that provide analogies to condensed matter systems.
