Eliashberg equations derived from the functional renormalization group
Carsten Honerkamp, Manfred Salmhofer
We describe how the fermionic functional renormalization group (fRG) flow of a Cooper+forward scattering problem can be continued into the superconducting state. This allows us to…

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.…

Flow of the quasiparticle weight in the N-patch renormalization group scheme
Carsten Honerkamp, Manfred Salmhofer
Using the N-patch renormalization group method we investigate the flow of the quasiparticle weight in one-dimensional, weakly two-dimensional and fully two-dimensional Hubbard mode…
