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…
The Numerically Optimized Regulator and the Functional Renormalization Group
I. G. Marian, U. D. Jentschura, I. Nandori
We aim to optimize the functional form of the compactly supported smooth (CSS) regulator within the functional renormalization group (RG), in the framework of bosonized two-dimensi…
Spontaneous symmetry breaking and optimization of functional renormalization group
I. Nandori, I. G. Marian, V. Bacso
The requirement for the absence of spontaneous symmetry breaking in the d=1 dimension has been used to optimize the regulator dependence of functional renormalization group equatio…
Phase Structure and Compactness
I. Nandori, S. Nagy, K. Sailer +1
In order to study the influence of compactness on low-energy properties, we compare the phase structures of the compact and non-compact two-dimensional multi-frequency sine-Gordon…
Wave-function renormalization for the Coulomb-gas in Wegner-Houghton's RG method
I. Nandori, J. Polonyi, K. Sailer
The RG flow for the sine-Gordon model is determined by means of the method of Wegner and Houghton in next-to-leading order of the derivative expansion. For small values of the fuga…
