Anisotropic superconductivity calculations with the full-bandwidth Migdal-Eliashberg formalism using the EPW code
ORAL
Abstract
Recent developments in the superconductivity module of the EPW code include solving the full-bandwidth (FBW) anisotropic Migdal-Eliashberg equations. This approach enables the description of phonon-mediated superconductors beyond the constant density of states approximation. Here we overview the implemented formalism, a brief how-to for invoking the new features, and benchmarking tests' results demonstrating the computational scaling and performance of the FBW method.
