Renormalization group analysis of the 2D Hubbard model
Christoph J. Halboth, Walter Metzner
Salmhofer [Commun. Math. Phys. 194, 249 (1998)] has recently developed a new renormalization group method for interacting Fermi systems, where the complete flow from the bare actio…

Spectral Function of 2D Fermi Liquids
Christoph J. Halboth, Walter Metzner
We show that the spectral function for single-particle excitations in a two-dimensional Fermi liquid has Lorentzian shape in the low energy limit. Landau quasi-particles have a uni…

Fermi Surface of the 2D Hubbard Model at Weak Coupling
Christoph J. Halboth, Walter Metzner
We calculate the interaction-induced deformation of the Fermi surface in the two-dimensional Hubbard model within second order perturbation theory. Close to half-filling, interacti…
