Talk Title: “Probing many-body physics with atoms and molecules”


The development of optical lattices and the use of Feshbach resonances allow a wealth of many-body phenomena to be explored in experiments with ultracold gases. Here we describe the experimental studies on Bose-Einstein condensation underway in Durham where we eventually aim to probe many-body physics with both atoms and molecules. Central to our research is the use of magnetic-field-induced Feshbach resonances to both control of the atomic interactions and to couple free atoms into weakly bound molecular states. We will focus on two established experiments. The first uses a quantum degenerate mixture of Rb and Cs to create ultracold heteronuclear molecules where long-range dipole-dipole interactions play an important role. The second experiment focuses on the formation of bright matter wave solitons using a condensate with attractive interactions and aims to use such solitons to probe the boundaries between many-body and GPE descriptions of ultracold gases.
