Oscillations and decay of superfluid currents in a one-dimensional Bose gas on a ring

Résumé

We study the time evolution of a supercurrent imprinted on a one-dimensional ring of interacting bosons in the presence of a defect created by a localized barrier. Depending on interaction strength and temperature, we identify various dynamical regimes where the current oscillates, is self-trapped or decays with time. We show that the dynamics is captured by a dual Josephson model, and involves phase slips of thermal or quantum nature.
