Decay of Persistent Currents in Annular Atomic Superfluids
Decay of Persistent Currents in Annular Atomic Superfluids
We investigate the role of vortices in the decay of persistent current states of annular atomic superfluids by solving numerically the GrossāPitaevskii equation, and we directly compare our results with the 6Li experiment at LENS data. We theoretically model the optical phase-imprinting technique employed to experimentally excite finite-circulation states in ā¦
