The Critical Temperature of Two-Band Superconductors with Pseudogap

Abstract:

The exact formula of T_c’s equation of two-band s-wave superconductors with Pseudogap in weak-coupling limit are derived by considering the influence of interband interaction. The pairing interaction in each band consisted of 2 parts the electron-phonon interaction and non-electron-phonon interaction are included in our model. It was found that the critical temperature is increased as Pseudogap, phonon coupling of 1^st band constant and interband phonon coupling constant increased.
