Functional renormalization group for commensurate antiferromagnets: Beyond the mean-field picture
Stefan A. Maier, Andreas Eberlein, Carsten Honerkamp
We present a functional renormalization group (fRG) formalism for interacting fermions on lattices that captures the flow into states with commensurate spin-density wave order. Dur…

Functional renormalization group study of fluctuation effects in fermionic superfluids
Andreas Eberlein
This thesis is concerned with ground state properties of two-dimensional fermionic superfluids, in which fluctuation effects like the renormalization of the order parameter or infr…

Fermionic two-loop functional renormalization group for correlated fermions: Method and application to the attractive Hubbard model
Andreas Eberlein
We derive an efficient method for treating renormalization contributions at two-loop level within the functional renormalization group in the one-particle irreducible formalism for…
