Gutzwiller scheme for electrons and phonons: the half-filled Hubbard-Holstein model
P. Barone, R. Raimondi, M. Capone +2
We analyze the ground-state properties of strongly-correlated electrons coupled with phonons by means of a generalized Gutzwiller wavefunction which includes phononic degrees of fr…
Strongly Correlated Superconductivity rising from a Pseudo-gap Metal
Marco Schiro', Massimo Capone, Michele Fabrizio +1
We solve by Dynamical Mean Field Theory a toy-model which has a phase diagram strikingly similar to that of high superconductors: a bell-shaped superconducting region adjacen…
Role of the impurity-potential range in disordered d-wave superconductors
Luca Dell'Anna, Michele Fabrizio, Claudio Castellani
We analyze how the range of disorder affects the localization properties of quasiparticles in a two-dimensional d-wave superconductor within the standard non-linear sigma-model app…
Dynamical behavior across the Mott transition of two bands with different bandwidths
Michel Ferrero, Federico Becca, Michele Fabrizio +1
We investigate the role of the bandwidth difference in the Mott metal-insulator transition of a two-band Hubbard model in the limit of infinite dimensions, by means of a Gutzwiller…
Spectral properties of a two-orbital Anderson impurity model across a non-Fermi liquid fixed point
Lorenzo De Leo, Michele Fabrizio
We study by NRG the spectral properties of a two-orbital Anderson impurity model in the presence of an exchange splitting which follows either regular or inverted Hund's rules. The…
