Truncation Effects in the Functional Renormalization Group Study of Spontaneous Symmetry Breaking
N. Defenu, P. Mati, I. G. Marian +2
We study the occurrence of spontaneous symmetry breaking (SSB) for O(N) models using functional renormalization group techniques. We show that even the local potential approximatio…

Validating the 2PI resummation: the Bloch-Nordsieck example
A. Jakovac, P. Mati
In this work we provide a numerical method to obtain the Bloch-Nordsieck spectral function at finite temperature in the framework of the 2PI approximation. We find that the 2PI res…
