Stephanie Reimanns: Persistent currents in bosonic mixtures

Abstract

In this talk, I will review how quantum fluctuations in mixtures of bosonic atoms can lead to the formation of self-bound droplets. Emphasis will be on persistent currents in ring-trapped binary mixtures as well as dipolar supersolids. For binary condensates with equal intra-component interactions but an unequal number of atoms in the two components, there is an excess part that cannot bind. A droplet then becomes amalgamated with a residual condensate. This results in particular rotational behavior that sheds new light on the coexistence of localization and superfluidity.
