Relevance of phonon dynamics in strongly correlated systems coupled to phonons: A Dynamical Mean Field Theory analysis
Giorgio Sangiovanni, Massimo Capone, Claudio Castellani
The properties of the electron-phonon interaction in the presence of a sizable electronic repulsion at finite doping are studied by investigating the metallic phase of the Hubbard-…
Polaron Crossover and Bipolaronic Metal-Insulator Transition in the Holstein model at half-filling
M. Capone, P. Carta, S. Ciuchi
The evolution of the properties of a finite density electronic system as the electron-phonon coupling is increased are investigated in the Holstein model using the Dynamical Mean-F…
Energetic balance of the superconducting transition across the BCS-Bose E instein crossover in the attractive Hubbard model
A. Toschi, M. Capone, C. Castellani
We investigate by means of Dynamical Mean-Field Theory the crossover from BCS superconductivity to Bose-Einstein (BE) condensation of preformed pairs in the attractive Hubbard mode…
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…
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…
Pairing and polarization in systems with retarded interactions
S. Ciuchi, G. Sangiovanni, M. Capone
In a system where a boson (e.g, a phonon) of finite frequency is coupled to electrons, two phenomena occur as the coupling is increased: electron pairing and polarization of…
