Аннотация
This work studies mesoscopic spin transport for strongly interacting Fermi gases via a quantum point contact. For a small spin-bias regime, the current in the vicinity of the superfluid transition is largely suppressed due to pseudogap formations. For a large spin-bias regime, on the other hand, the current is enhanced by the appearance of polaronic excitations.
