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 study the dynamics of quantum optical many-body systems and their applications in nascent quantum technologies. We also develop quantum algorithms for solving non-linear optimization problems focusing on applications in fluid flows and design questions.

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.

Our group develops quantum network technology to leverage and scale up the advantages of individual quantum devices, for example exploring quantum super computers, distributed sensors or decentralized cryptography.

We develop and use ultracold atom platforms for applications in quantum simulation, in particular of condensed matter model systems, and quantum computation. For this purpose, we implement techniques to manipulate and image quantum many-body systems at the single-atom level.

The theory group of '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 study various phenomena using ultracold atoms and Rydberg excitations ranging from quantum simulation and computation in optical tweezer arrays to the interplay of ultrashort pulses and Bose Einstein condensates.
