QED in the Exact Renormalization Group
Yuji Igarashi, Katsumi Itoh
The functional flow equation and the Quantum Master equation are consistently solved in perturbation for the chiral symmetric QED with and without four-fermi interactions. Due to t…
BRST in the Exact RG
Yuji Igarashi, Katsumi Itoh, Tim R. Morris
We show that the Quantum Master Equation and the Wilsonian renormalization group (RG) flow equation can be combined such that for the continuum effective action, quantum BRST invar…
On the wave function renormalization for Wilson actions and their 1PI actions
Y. Igarashi, K. Itoh, H. Sonoda
We clarify the relation between the wave function renormalization for Wilson actions and that for the 1PI actions in the exact renormalization group formalism. Our study depends cr…
Functional flows in QED and the modified Ward-Takahashi identity
Yuji Igarashi, Katsumi Itoh, Jan M. Pawlowski
In the functional renormalisation group approach to gauge theory, the Ward-Takahashi identity is modified due to the presence of an infrared cutoff term. It take the most accessibl…
Blocking-inspired supersymmetric actions: a status report
Georg Bergner, Falk Bruckmann, Yoshio Echigo +3
We provide a status report on the advances in blocking-inspired supersymmetric actions. This is done at the example of interacting supersymmetric quantum mechanics as well as the W…
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…
