Abstract

Square lattice Hubbard model is investigated near half-filled in the limit of large U. A slave-fermion scheme is used, where electron operators are replaced by bose operators with auxiliary fermi operators. The ground state by a mean field approximation with RVB order parameter for spin shows long-range antiferromagnetic order, which is incommensurate except for half-filled case.
