Band-filling effects on electron-phonon properties of normal and superconducting state
E. Cappelluti, S. Ciuchi, C. Grimaldi +1
We address the effect of band filling on the effective electron mass and the superconducting critical temperature in a electron-phonon system. We compare the vertex cor…

Spin susceptibility in small Fermi energy systems: effects of nonmagnetic impurities
E. Cappelluti, C. Grimaldi, L. Pietronero
In small Fermi energy metals, disorder can deeply modify superconducting state properties leading to a strong suppression of the critical temperature . In this paper, we show…
