Anisotropic Migdal-Eliashberg theory using Wannier functions

Abstract:

We combine the fully anisotropic Migdal-Eliashberg theory with electron-phonon interpolation based on maximally localized Wannier functions, in order to perform reliable and highly accurate calculations of the anisotropic temperature-dependent superconducting gap and critical temperature of conventional superconductors. Compared with the widely used McMillan approximation, our methodology yields a more comprehensive and detailed description of superconducting properties, and is especially rel...
