Abstract

Efforts to understand strongly interacting Fermi systems using generalizations of the Gutzwiller variational wavefunction are described. An extended Hubbard model with strong intersite repulsions on a two-dimensional copper-oxygen lattice has a charge transfer instability that is studied using the method, and the possibility that this model has a ground state displaying s-wave superconductivity is investigated.
