Functional Renormalization Group Flows and Gauge Consistency in QED

Yoshio Echigo, Yuji Igarashi, Katsumi Itoh +2

We consider quantum electrodynamics with chiral four-Fermi interactions in the functional renormalization group approach. In gauge theories, the functional flow equation for the ef…

Realization of Chiral Symmetry in the ERG

Yoshio Echigo, Yuji Igarashi

We discuss within the framework of the ERG how chiral symmetry is realized in a linear model. A generalized Ginsparg-Wilson relation is obtained from the Ward-Takahashi identit…
