The wavefunction renormalization constant for the one- and two- band Hubbard hamiltonians in two dimensions

E. Louis, G. Chiappe, J. Galan +2

The wavefunction renormalization in the Hubbard model is studied, by using well tested mean field tecniques. The 'orthogonality catastrophe' is shown to exist, even in 2D, for dopi…
