Magnetic and superconducting instabilities of the Hubbard model at the van Hove filling
Carsten Honerkamp, Manfred Salmhofer
We use a novel temperature-flow renormalization group technique to analyze magnetic and superconducting instabilities in the two-dimensional t-t' Hubbard model for particle densiti…

The temperature-flow renormalization group and the competition between superconductivity and ferromagnetism
Carsten Honerkamp, Manfred Salmhofer
We derive a differential equation for the one-particle-irreducible vertex functions of interacting fermions as a function of the temperature. Formally, these equations correspond t…
