Quasiparticle anisotropy and pseudogap formation from the weak-coupling renormalization group point of view
A. A. Katanin, A. P. Kampf
Using the one-loop functional renormalization group technique we evaluate the self-energy in the weak-coupling regime of the 2D t-t' Hubbard model. At van Hove (vH) band fillings a…

Renormalization group analysis of magnetic and superconducting instabilities near van Hove band fillings
A. A. Katanin, A. P. Kampf
Phase diagrams of the two-dimensional one-band t-t' Hubbard model are obtained within the two-patch and the temperature-cutoff many-patch renormalization group approach. At small t…
