Abstract: | An iteration procedure allows to find an equation for the critical temperatureT c of superconductors starting from the linearized Eliashberg equations without using any cutoff parameters or a Coulomb pseudopotential. Explicit calculation ofT c for a simple model leads to Morel, Anderson and McMillan's1,2 expression thereby allowing for a physical interpretation of the commonly used approximation for the Coulombpseudopotential. |
