Quantum Optics

Our group conducts experiments on various topics within the broader scope of quantum optics and quantum statistics. The research includes quantum simulation with ultracold atomic gases, the equilibrium thermodynamics of light including Bose-Einstein condensation of photons, but also experiments on spectroscopy of high pressure gases, which aims at the realization of a light source in the VUV. Many of the topics are overlapping, but can be broadly grouped into a set of overarching research questions.
