Phase diagram of imbalanced strongly interacting fermions on a one-dimensional optical lattice
Alberto Anfossi, Luca Barbiero, Arianna Montorsi
We show that the Hubbard Hamiltonian with particle-assisted tunneling rates --recently proposed to model a fermionic mixture near a broad Feshbach resonance-- displays a ground sta…

Nanoscale phase separation and superconductivity in the one-dimensional Hirsch model
Alberto Anfossi, Cristian Degli Esposti Boschi, Arianna Montorsi
We investigate numerically at various fillings the ground state of the one-dimensional Hubbard model with correlated hopping x (Hirsch model). It is found that, for a wide range of…
