Spontaneous Symmetry Breaking without classical fields: a Functional Renormalization Group approach
A. Jakovac, P. Mati, P. Posfay
We propose an approach to describe Spontaneous Symmetry Breaking (SSB) that does not rely on the order parameter dependent free energy (Landau theory). We use the Functional Renorm…

Harmonic expansion of the effective potential in Functional Renormalization Group at finite chemical potential
G. G. Barnafoldi, A. Jakovac, P. Posfay
In this paper we propose a method to study the Functional Renormalization Group at finite chemical potential. The method consists of mapping the FRG equations within the Fermi surf…

Non-Gaussian fixed points in fermionic field theories without auxiliary Bose-fields
A. Jakovac, A. Patkos, P. Posfay
The functional equation governing the renormalization flow of fermionic field theories is investigated in dimensions without introducing auxiliary Bose-fields on the example of…
