d-wave superconductivity near charge instabilities
A. Perali, C. Castellani, C. Di Castro +1
We investigate the symmetry of the superconducting order parameter in the proximity of a phase-separation or of an incommensurate charge-density-wave instability. The attractive ef…

Influence of electron-phonon interaction on superexchange
W. Stephan, M. Capone, M. Grilli +1
We investigate the influence of electron-phonon coupling on the superexchange interaction of magnetic insulators. Both the Holstein-Hubbard model where the phonons couple to the el…

Charge-density-waves and superconductivity as an alternative to phase separation in the infinite-U Hubbard-Holstein model
F. Becca, M. Tarquini, M. Grilli +1
We investigate the density instabilities present in the infinite-U Hubbard-Holstein model both at zero and finite momenta as well as the occurrence of Cooper instabilities with a s…
