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…
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…
Competition between d-wave superconductivity and antiferromagnetism in the 2D Hubbard model
M. Capone, G. Kotliar
We study the competition of antiferromagnetism and d-wave superconductivity at zero-temperature in the two-dimensional Hubbard model using Cellular Dynamical Mean Field Theory. The…
Electron-phonon interaction and antiferromagnetic correlations
G. Sangiovanni, O. Gunnarsson, E. Koch +2
We study effects of the Coulomb repulsion on the electron-phonon interaction (EPI) in a model of cuprates at zero and finite doping. We find that antiferromagnetic correlations str…
