ALP Seminar: Dissipation in ultracold weakly-interacting quantum gases

Dissipation in ultracold quantum gases can arise as a result of externally induced perturbations or coupling of the condensate to the co-existing incoherent thermal cloud. In this talk I will discuss dissipative dynamics in different settings, motivated by experimental investigations. In particular, I will highlight the origin and manifestations of dissipation in the context of Josephson junctions (LENS experiments), atomic mixtures (Aarhus and Durham experiments), and (time-permitting) ongoing characterisation in a box trap setting (Cambridge set-up).
