Scaling of Coulomb pseudo-potential in s-wave narrow-band superconductors | Tae-Ho Park

4 Nov 2001 | Subject: | Strongly Correlated Electrons; Superconductivity | cond-mat.str-el cond-mat.supr-con | Abstract: | The Coulomb pseudo-potential $mu^*$ is extracted by fitting the numerically calculated transition temperature $T_c$ of the Eliashberg-Nambu equation which is extended to incorporate the narrow-band effects, that is, the vertex correction and the frequency dependence of the screened Coulomb interaction. It is shown that even for narrow-band superconductors, where the fermi energy $ epsilon_F$ is comparable with the phonon frequency $ omega_{ph}$, the Coulomb pseudo-potential is a pertinent parameter, and is still given by $mu^* = mu/[1+mu ln(epsilon_F/omega_{ph})] $, provided $omega_{ph}$ is appropriately scaled. | Source: | arXiv, cond-mat/0111051 | Services: | Forum | Review | PDF | Favorites |
