Order parameter symmetries for magnetic and superconducting instabilities: Bethe-Salpeter analysis of functional renormalization-group solutions
A. A. Katanin, A. P. Kampf
The Bethe-Salpeter equation is combined with the temperature-cutoff functional renormalization group approach to analyze the order parameter structure for the leading instabilities…

Anomalous self-energy and Fermi surface quasi-splitting in the vicinity of a ferromagnetic instability
A. A. Katanin, A. P. Kampf, V. Yu. Irkhin
We discuss the low-temperature behavior of the electronic self-energy in the vicinity of a ferromagnetic instability in two dimensions within the two-particle self-consistent appro…

On the fulfillment of Ward identities in the functional renormalization group approach
A. A. Katanin
I consider the fulfillment of conservation laws and Ward identities in the one- and two-loop functional renormalization group approach. It is shown that in a one-particle irreducib…
