Anomalous impurity effects in nonadiabatic superconductors
M. Scattoni, C. Grimaldi, L. Pietronero
We show that, in contrast with the usual electron-phonon Migdal-Eliashberg theory, the critical temperature Tc of an isotropic s-wave nonadiabatic superconductor is strongly reduce…

The physical origin of the electron-phonon vertex correction
C. Grimaldi, L. Pietronero, M. Scattoni
The electron-phonon vertex correction has a complex structure both in momentum and frequency. We explain this structure on the basis of physical considerations and we show how the…
