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…
Local potential approximation for the renormalization group flow of fermionic field theories
A. Jakovac, A. Patkos
The second functional derivative of the effective potential of pure fermionic field theories is rewritten in a factorized form which facilitates the evaluation of the renormalisati…
Spontaneously broken ground states of the U(n)_L x U(n)_R linear sigma model at large n
G. Fejos, A. Patkos
Symmetry breaking patterns of the U(n)_L x U(n)_R symmetric meson model are investigated in a formulation involving three auxiliary composite fields. The effective potential is con…
Renormalized effective actions for the O(N) model at next-to-leading order of the 1/N expansion
G. Fejos, A. Patkos, Zs. Szep
A fully explicit renormalized quantum action functional is constructed for the O(N)-model in the auxiliary field formulation at next-to-leading order (NLO) of the 1/N expansion. Co…
Phase structure and phase transitions of the SU(2) x O(N) symmetric scalar field theory
A. Patkos, Zs. Szep
Radiatively induced SU(2) symmetry breaking is shown to be a genuine feature of SU(2) x O(N) globally symmetric renormalisable field theories in the large N limit, describing inter…
Nonequilibrium Goldstone phenomenon in Hybrid Inflation
Sz. Borsanyi, A. Patkos, D. Sexty
We study the onset of Goldstone phenomenon in a hybrid inflation scenario. The physically motivated range of parameters is analyzed in order to meet the cosmological constraints. C…
