The 2-site Hubbard and t-J models
Adolfo Avella, Ferdinando Mancini, Taiichiro Saikawa
The fermionic and bosonic sectors of the 2-site Hubbard model have been exactly solved by means of the equation of motion and Green's function formalism. The exact solution of the…

Anisotropic pseudogap in the half-filling 2-d Hubbard model at finite T
T. Saikawa, A. Ferraz
We have studied the pseudogap formation in the single-particle spectra of the half-filling two-dimensional Hubbard model. Using a Green's function with the one-loop self-energy cor…
