Driving Phase Slips in a Superfluid Atom Circuit with a Rotating Weak Link

Abstract
We have induced well-defined phase slips between quantized persistent current states around a toroidal atomic 23Na Bose-Einstein condensate by rotating a weak link (a localized region of reduced superfluid density) around the ring at low angular frequency. This is analogous to the behavior of a superconducting loop with a weak link in the presence of an external magnetic field. At higher angular frequencies, well-defined phase slips no longer occur, and vortices enter the condensate.Citation
