My research centers on the boundary between many-body physics, quantum optics, and AMO physics. Over the course of the last 10 years, advances in experiments with ultracold quantum gases have made possible the realization of strongly interacting systems, which can be used to explore complex many-body phenomena. Motivated by and in connection with these experiments, we explore novel phenomena on a theoretical level with analytical and numerical techniques.
In particular, we are interested in the non-equilibrium dynamics of quantum gases, treating both coherent many-body dynamics (e.g., transport dynamics, or the exploration of metastable many-body states and their associated quantum phases), and dissipative many-body dynamics (e.g., heating of quantum gases in optical potentials, or engineering dissipative driving to produce complex many-body states). We are also interested more generally in quantum simulation and the implementation of quantum computing in many-body systems.
