Computing the Effective Action with the Functional Renormalization Group
Alessandro Codello, Roberto Percacci, Leslaw Rachwal +1
The "exact" or "functional" renormalization group equation describes the renormalization group flow of the effective average action . The ordinary effective action can b…
A renormalization group improved computation of correlation functions in theories with non-trivial phase diagram
Alessandro Codello, Alberto Tonero
We present a simple and consistent way to compute correlation functions in interacting theories with non-trivial phase diagram. As an example we show how to consistently compute th…
Functional and Local Renormalization Groups
Alessandro Codello, Giulio D'Odorico, Carlo Pagani
We discuss the relation between functional renormalization group (FRG) and local renormalization group (LRG), focussing on the two dimensional case as an example. We show that away…
