Abstract
By introducing a repulsive barrier at the interface between two density-coupled rings of ultracold atoms, a persistent current can oscillate between the rings. The phenomenon persists indefinitely in the limit of zero temperature, but it decays at finite temperature and can even be suppressed completely in the limit of large damping.
