摘要: For non-phonon interaction mechanisms which span a frequency range comparable to the Fermi energy, solution of Eliashberg equation must cover both frequencies and momentum values. Kirzhnits, Maksimov, Khomskii (KMK) have derived an intergral for superconducting transition where is eliminated in favor momentum. We found systematic correction KMK investigated effect onTcfor model interactions.
