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…

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…
