Approximating the frequency dependence of the effective interaction in the functional renormalization group for many-fermion systems
Timo Reckling, Carsten Honerkamp
The functional renormalization group has become a widely used tool for the analysis of the leading low-temperature correlations in weakly to moderately coupled many-fermion lattice…

Truncated unity functional renormalization group for multiband systems with spin-orbit coupling
G. A. H. Schober, J. Ehrlich, T. Reckling +1
Although the functional renormalization group (fRG) is by now a well-established method for investigating correlated electron systems, it is still undergoing significant technical…
