Transport properties in correlated systems: An analytical model
F. Rizzo, E. Cappelluti, L. Pietronero
Several studies have so far investigated transport properties of strongly correlated systems. Interesting features of these materials are the lack of resistivity saturation well be…

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…
