Constrained s-wave weak-coupling superconductivity in multiband superconductors
Aase, Niels Henrik; Johnsen, Christian Svingen; Sudbø, Asle (Peer reviewed; Journal article, 2023)We consider superconductivity in a system with N Fermi surfaces, including intraband and interband effective electron-electron interactions. The effective interaction is described by an N × N matrix whose elements are ...
