Effects of mass imbalance on metal-insulator transitions in the ionic Hubbard model
We investigated the effects of mass imbalance on the metal-insulator phase diagram in the half-filled ionic Hubbard model using dynamical mean field theory (DMFT) and the equations of motion (EOM) method to solve the impurity problem. Our results show that the band insulator region changes less sig...
