Superfluid density, Josephson relation and pairing fluctuations in a multi-component fermion superfluid

Abstract In this work, a Josephson relation is generalized to a multi-component fermion superfluid. Superfluid density is expressed through a two-particle Green function for pairing states. When the system has only one gapless collective excitation mode, the Josephson relation is simplified, which i...
