Interacting two-particle states in the symmetric phase of the chiral Nambu--Jona-Lasinio model
A. Jakovac, A. Patkos
The renormalisation group flow of the chiral Nambu--Jona-Lasinio (NJL) model with one fermion flavor is mapped out in the symmetric phase with the help of the Functional Renormalis…
Bound states in Functional Renormalization Group
A. Jakovac, A. Patkos
Equivalence criteria are established for an effective Yukawa-type theory of composite fields representing two-particle fermion bound states with the original "microscopic" theory o…
Renormalisation Group determination of scalar mass bounds in a simple Yukawa-model
A. Jakovac, I. Kaposvari, A. Patkos
The scalar mass is determined in the simplest scalar-fermion Yukawa-model in the whole range of stability of the scalar potential. Two versions of the Functional Renormalisation Gr…
Scalar mass stability bound in a simple Yukawa-theory from renormalisation group equations
A. Jakovac, I. Kaposvari, A. Patkos
Functional Renormalisation Group (FRG) equations are constructed for a simple Yukawa-model with discrete chiral symmetry, including also the effect of a nonzero composite fermion b…
Phantom field fluctuation induced Higgs effect
A. Patkos, Zs. Szep
Symmetry breaking solutions are investigated in the limit for the ground state of a system consisting of a Lorentz-scalar, N component ``phantom'' field and an O(N) s…
Fate of the classical false vacuum
Sz. Borsanyi, A. Patkos, J. Polonyi +1
Thermalisation of configurations with initial white noise power spectrum is studied in numerical simulations of a classical one-component theory in 2+1 dimensions, coupled to…
