Topological Change of the Fermi Surface in Low Density Rashba Gases: Application to Superconductivity
E. Cappelluti, C. Grimaldi, F. Marsiglio
Strong spin-orbit coupling can have a profound effect on the electronic structure in a metal or semiconductor, particularly for low electron concentrations. We show how, for small…
Isotope effects in the Hubbard-Holstein model within dynamical mean-field theory
P. Paci, M. Capone, E. Cappelluti +2
We study the isotope effects arising from the coupling of correlated electrons with dispersionless phonons by considering the Hubbard-Holstein model at half-filling within the dyna…
Spin-Hall Conductivity in Electron-Phonon Coupled Systems
C. Grimaldi, E. Cappelluti, F. Marsiglio
We derive the ac spin-Hall conductivity of two-dimensional spin-orbit coupled systems interacting with dispersionless phonons of frequency . For the linear Ras…
Tunneling and Non-Universality in Continuum Percolation Systems
C. Grimaldi, I. Balberg
The values obtained experimentally for the conductivity critical exponent in numerous percolation systems, in which the interparticle conduction is by tunnelling, were found to be…
