Multiloop functional renormalization group for general models
Fabian B. Kugler, Jan von Delft
We present multiloop flow equations in the functional renormalization group (fRG) framework for the four-point vertex and self-energy, formulated for a general fermionic many-body…

Fermi-edge singularity and the functional renormalization group
Fabian B. Kugler, Jan von Delft
We study the Fermi-edge singularity, describing the response of a degenerate electron system to optical excitation, in the framework of the functional renormalization group (fRG).…

Multiloop functional renormalization group that sums up all parquet diagrams
Fabian B. Kugler, Jan von Delft
We present a multiloop flow equation for the four-point vertex in the functional renormalization group (fRG) framework. The multiloop flow consists of successive one-loop calculati…
