Quantum Fluids

Welcome to our Emmy-Noether research group web page. We are mainly interested in physics of quantum fluids which are systems that are liquid at temperatures close to absolute zero and live in the realm of quantum mechanics. We are based at Technical University Munich and our work is funded by Deutschen Forschungsgemeinschaft (DFG).


If you are a curious and motivated Bachelor or Master student at TUM or LMU looking for a thesis topic in condensed matter theory, you are very welcome to contact us.
