STRONG ELECTRONIC CORRELATION IN THE INPLANE ELECTRONIC-PROPERTIES OFTHE HIGH T-C SUPERCONDUCTORS

A self-consistent incommensurate Hartree-Fock theory of the doped stro ngly-coupling Hubbard model defined on a two-dimensional square lattic e can settle the contradiction of the established transport properties with the photoemission Fermi surfaces of the doped superconducting cu prates. The key point is the strong electronic correlation. The transp ort properties, Fermi surfaces, and incommensurate magnetic order are qualitatively described in the framework.
