FIELDS OF RESEARCH
My main research interest is the non-equilibrium behavior of quantum many-body systems. In the past decades, condensed matter theory has mainly focused on understanding the equilibrium or linear response properties of condensed matter systems. Recent experimental advances in ultracold gases and nanostructures have opened up the exciting new field of non-equilibrium quantum many-body physics, where many fundamental questions like return to equilibrium, physics beyond the linear response regime, etc., are largely unanswered. This has led to a lot of activity and we are pursuing some of these questions using mainly analytical methods, especially the flow equation approach (method of infinitesimal unitary transformations).
