Abstract: Two formulations of superfluidity are reviewed: Landau’s phenomenological two-fluid model and a relativistic effective field theory description. We demonstrate how the two-fluid formalism can be recovered from the nonrelativistic limit of the relativistic effective theory… read more here.
