We give upper and lower bounds fur the ground-state energy of the infinite-U Hubbard model. In two dimensions, using these bounds we are able to rule out the possibility of phase separation between the undoped-insulating stare and a hole-rich state.

Abstract
We give upper and lower bounds fur the ground-state energy of the infinite-U Hubbard model. In two dimensions, using these bounds we are able to rule out the possibility of phase separation between the undoped-insulating stare and a hole-rich state.File in questo prodotto:
