Strong-Coupling Perturbation Theory of the Hubbard Model
Stephane Pairault, David Senechal, A. -M. S. Tremblay
The strong-coupling perturbation theory of the Hubbard model is presented and carried out to order (t/U)^5 for the one-particle Green function in arbitrary dimension. The spectral…

Strong-Coupling Expansion for the Hubbard Model
Stéphane Pairault, David Sénéchal, A. -M. S. Tremblay
A strong-coupling expansion for models of correlated electrons in any dimension is presented. The method is applied to the Hubbard model in dimensions and compared with numeric…
