Our group conducts experiments on the following topics: thermodynamics of light, as Bose-Einstein condensation of photons in microcavities, and the statistics and dynamics of photons in tailored potentials. We also investigate topology and quantum simulation with ultracold atomic gases.

We are always looking for Bachelor, Master, PhD students, and postdocs. For more information, see here.
