Welcome to the group homepage!

We are currently interested in exploring quantum impurity physics as a paradigm for a variety of physical systems, such as correlated fermions and bosons, and open quantum systems. A central theme is to establish links between different phenomena - such as Kondo physics, quantum dissipation, and Mott transitions - which can all be traced back to similar fundamental principles.
