Extended Hubbard models, eta-pairing and supersymmetry
Tóm tắt
Exact results on extended Hubbard models are discussed. It is shown that condensation of local electron pairs at zero momentum constitutes a mechanism for superconductivity in a supersymmetric extended Hubbard model in any number of dimensions. The exact solution in one dimension is presented.
