Superfluid Density in Pairing Theory of Superfluidity
It has long been recognized that the question of whether a system is superfluid or not may be formulated in terms of the properties of its linear response kernel, for such a kernel can tell us what the ultimat...

A conserving approximation evaluation of superfluid density within the pair theory of superfluids
The evaluation of the superfluid density, defined by the weak field response of the system, within the pairing theory of “pure” superfluids of Fermi or Bose statistics is considered. The need for evaluating th...
