Renormalization of the 2PI-Hartree approximation in a broken phase with nonzero superflow
G. Fejos
Nonperturbative renormalization and explicit construction of the effective potential of the Hartree approximation of the two-particle-irreducible formalism are carried out in an in…

Fluctuation induced first order phase transition in U(n)xU(n) models using chiral invariant expansion of functional renormalization group flows
G. Fejos
Phase transition in U(n)xU(n) models is investigated for arbitrary flavor number n. We present a nonperturbative, 3+1 dimensional finite temperature treatment of obtaining the effe…

Renormalized O(N) model at next-to-leading order of the 1/N expansion: Effects of the Landau pole
G. Fejos, A. Patkos, Zs. Szep
Apparently convergent contributions of resummed perturbative series at the next-to-leading order of the 1/N expansion in the O(N) model are reanalyzed in terms of renormalizability…
