Effective interactions and fluctuation effects in spin-singlet superfluids
Andreas Eberlein, Walter Metzner
We derive and evaluate one-loop functional flow equations for the effective interactions, self-energy and gap function in spin-singlet superfluids. The flow is generated by a fermi…

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…
