Smoothing of Singular Legendre Transforms in Renormalization Group Flows
Christoph Husemann, Manfred Salmhofer
We consider O(N)-symmetric potentials with a logarithmic singularity in the second field derivative. This class includes BCS and Gross Neveu potentials. Formally, the exact renorma…

Efficient Fermionic One-Loop RG for the 2D Hubbard Model at Van Hove Filling
Christoph Husemann, Manfred Salmhofer
We propose a novel parametrization of the four-point vertex function in the one-loop one-particle irreducible renormalization group (RG) scheme for fermions. It is based on a decom…
