Bulk Superconductivity in Weakly Localized Regime

Abstract

The critical temperature, T_c, and the upper critical field, H_c2, have been examined for three-dimensional superconductors in the weakly localized regime. The life time, τ, is assumed to be short enough such that τ⁻¹>>ω_D; ω_D being the Debye frequency. The results indicate that there exists an appreciable suppression of T_c even in the weakly localized regime. The effect of strong spin-orbit scattering is also investigated and the suppression of T_c is seen not to be affected.
