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…
