Quantum Optics and Atom Optics links
Our research group at the Physikalisches Institut of Heidelberg University performs fundamental research in the fields of quantum and atomic physics. In our experiments, we use ultracold atom clouds to understand how complex quantum systems behave. In particular, we are interested in questions related to how strong interactions, reduced dimensionality (1D and 2D) and finite system size affects the physical properties of a quantum system.

June 2022 - Cooper pair paper published in Nature!
Here we directly observe Cooper pairs in a mesoscopic two-dimensional Fermi gas. We extract the full in situ momentum distribution of a strongly interacting Fermi gas with single-particle and spin resolution. Our ultracold gas enables us to freely tune between a completely non-interacting, unpaired system and weak attractions, where we find Cooper pair correlations at the Fermi surface. When increasing the attractive interactions even further, the pairs gradually turn into deeply bound molecules that break
