Competing order in correlated electron systems made simple: Consistent fusion of functional renormalization and mean-field theory
Jing Wang, Andreas Eberlein, Walter Metzner
We derive an efficient and unbiased method for computing order parameters in correlated electron systems with competing instabilities. Charge, magnetic and pairing fluctuations abo…

Superconductivity in the two-dimensional --Hubbard model
Andreas Eberlein, Walter Metzner
Using a recently developed renormalization group method for fermionic superfluids, we determine conditions for d-wave superconductivity in the two-dimensional Hubbard model at mode…

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…
