Two Definitions of Superfluid Density

Abstract
We point out that two different definitions of the superfluid density - through statistical response to static gauge phase and through dynamic response to altering gauge phase - yield, generally speaking, different quantities in . The physics leading to this difference is associated with the equilibrium statistics of supercurrent states. Some experimentally observable consequences of this fact are discussed.
