We investigate ultracold atomic gases to with the aim of understanding complex quantum systems. This interest is driven by the desire to understand strongly interacting and strongly correlated systems, with applications in solid-state physics (high temperature superfluidity), nuclear physics, astrophysics (neutron stars), quantum computing, and nanotechnologies.
Within our research we control these systems via external magnetic (Feshbach resonances) and laser fields (photoassociation, optical lattices). Feshbach resonances have enabled the investigation of molecular BEC, and the study of the BEC-BCS crossover. Control of optical lattices has enabled the observation of the superfluid to Mott-insulator phase transition. Today, the combination of these methods paves the way towards the investigation of ultracold molecular gases.
