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…

Parametrization of Nambu vertex in a singlet superconductor
Andreas Eberlein, Walter Metzner
We analyze general properties of the effective Nambu two-particle vertex and its renormalization group flow in a spin-singlet superconductor. In a fully spin-rotation invariant for…
