Shapiro steps of superfluid Fermi gases in a ring trap across the BCS--BEC crossover

Hikaru Kuriki, Masaya Kunimi, Tetsuro Nikuni

We investigate the transport properties of a superfluid Fermi gas confined in a ring trap with a moving potential barrier across the Bardeen-Cooper-Schrieffer (BCS) to Bose-Einstei…
