Research

We use ultracold atoms to study minimal laboratory models of quantum many-body physics. Our research covers ultracold atoms in optical cavities, topological optical lattices, and new concepts for quantum metrology.

We investigate ultracold atom and solid-state systems, with emphasis on many-body phenomena such as superfluidity and superconductivity. Our primary research interest is many-body dynamics using novel theoretical concepts for quantum dynamics.

We experimentally cool dilute gases to near absolute zero temperature. Here, quantum mechanical behaviour dominates, enabling us to study fundamental phenomena such as superfluidity, matter wave interference and correlated dynamics in highly tuneable model systems.

The theory group on 'Fundamental processes in quantum physics' focuses on the structure and dynamics in ultracold trapped systems but also on the development of novel fundamental concepts in quantum physics in general.

We develop lasers for squeezed and entangled light and research new technologies for gravitational-wave detectors and quantum communication, and address fundamental questions of quantum physics.

In our group we use ultracold quantum gases to study various kinds of interacting many-body systems, phenomena related to topology and hybrid quantum systems.
