Mixtures of Cold Gases

Efimov-Physics is studied with mixtures of cold Lithium and Rubidium quantum gases. Feshbach-resonances are exploitetd to generate strongly coupled quantum systems.

BEC in a Ring Cavity

Ultra cold atoms interact with the light of a high finesse ring resonator. Global coupling of the atoms leads to collective effects such as superradiance, subradiance, and collective atomic recoil lasing (CARL).
