On the critical temperature of anisotropic and inhomogeneous superconductors

V. M. Gvozdikov, I. I. Fal'ko


Abstract: It is shown that when allowance is made for spatial inhomogeneity and anisotropy of a superconductor and also under fairly general assumptions about the electron–electron interaction, the equation that determines the critical temperature of the superconducting transition coincides formally with the corresponding equation in BCS theory.
