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…
Nonadiabatic Superconductivity and Vertex Corrections in Uncorrelated Systems
P. Paci, E. Cappelluti, C. Grimaldi +1
We investigate the issue of the nonadiabatic superconductivity in uncorrelated systems. A local approximation is employed coherently with the weak dependence on the involved moment…
Superconductivity of RbC: breakdown of the Migdal-Eliashberg theory
E. Cappelluti, C. Grimaldi, L. Pietronero +2
In this paper, through an exhaustive analysis within the Migdal-Eliashberg theory, we show the incompatibility of experimental data of RbC with the basic assumptions of…
Nonadiabatic Pauli susceptibility in fullerene compounds
E. Cappelluti, C. Grimaldi, L. Pietronero
Pauli paramagnetic susceptibility is unaffected by the electron-phonon interaction in the Migdal-Eliashberg context. Fullerene compounds however do not fulfill the adiabatic as…
