Thermodynamics of Crossover from Weak- to Strong-Coupling Superconductivity
In this paper we study an evolution of low-temperature thermodynamical
quantities for an electron gas with a -function attraction as the
system crosses over from weak-coupling (BCS-type) to strong-coupling
(Bose-type) superconductivity in three and two dimensions.Comment: Replaced with journal version. Insignificant presentation changes.
