Thermodynamics of anisotropic-gap and multiband clean BCS superconductors

Superconductivity 2009-11-07 v2 Materials Science

Abstract

The free energy, non-gradient terms of the Ginzburg-Landau expansion, and the jump of the specific heat of a multiband anisotropic-gap clean BCS superconductor are derived in the framework of a separable-kernel approximation. Results for a two-band superconductor, d-wave superconductor, and some recent models for MgB_2 are derived as special cases.
