Persistent currents for strongly interacting gases on a ring

Anna Minguzzi, fot. www.cnrs.fr

Atomtronics aims at realizing and studying circuits for ultracold atoms, taking advantage of the striking experimental progresses in atom trapping by waveguides and manipulation. In this talk, I will focus on ultracold atoms confined on a ring trap and subjected to an artificial gauge field, induced eg by barrier stirring or by phase imprinting. I will present our theoretical studies of the persistent currents of strongly interacting particles, both bosons, fermions and mixtures. We use a combination of analytical and numerical methods to show that persistent currents can be used to probe the nature of the many-body states at strong interactions, and of their symmetries. Our studies have applications to quantum technologies, and in particular to high-precision atom interferometry.
