Research Interest

Our group investigates nonequilibrium phenomena in chemical and condensed matter physics. We try to understand how strongly correlated quantum systems react to dissipative environments and to external perturbations, particularly in the context of the transport properties of nanosystems. This is a deeply challenging and fundamental problem, and we therefore work on state-of-the-art computational methods such as quantum Monte Carlo algorithms.
