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…

Extended Gutzwiller wavefunction for the Hubbard-Holstein model
P. Barone, R. Raimondi, M. Capone +2
We introduce a new type of Gutzwiller variational wavefunction for correlated electrons coupled to phonons, able to treat on equal footing electronic and lattice degrees of freedom…

Effective electron-phonon coupling and polaronic transition in the presence of strong correlation
P. Barone, R. Raimondi, M. Capone +1
We study the Hubbard-Holstein model using slave-boson mean-field and a variation al Lang-Firsov transformation. We identify weak and strong e-ph coupling solutions, whose stability…
