"Luttinger" and insulating spin liquids in two dimensions
H. Freire, E. Correa, A. Ferraz
In the present work, we implement an explicit two-loop renormalization of a two-dimensional flat Fermi surface (FS) in the framework of a field theoretical renormalization group ap…

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…
