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…
