Popis:	Article Highlights Superfluid density of a superconductor (SC) is calculated with the BCS-Bose crossover extended with two-hole of Cooper pairs. In the weak-coupling extreme in 3D we found good agreement with conventional SCs with quadratic dispersion relation. For high-T $$_c$$ c SCs (cuprates) in the intermediate coupling in 2D with a linear relation; results compare well with the data.
