Functional renormalization group in the two-dimensional Hubbard model
Carsten Honerkamp
We review recent developments in functional renormalization group (RG) methods for interacting fermions. These approaches aim at obtaining an unbiased picture of competing Fermi li…

Interaction flow method for many-fermion systems
Carsten Honerkamp, Daniel Rohe, Sabine Andergassen +1
We propose an interaction flow scheme that sums up the perturbation expansion of many-particle systems by successively increasing the interaction strength. It combines the unbiased…

BCS pairing in Fermi systems with several flavors
Carsten Honerkamp, Walter Hofstetter
Motivated by the prospect of Bardeen-Cooper-Schrieffer (BCS) pairing in cold fermionic gases we analyze the superfluid phase of 3 fermionic flavors in the attractive Hubbard model.…
