Resummed perturbative series of scalar quantum field theories in two-particle-irreducible formalism
G. Fejos
In this thesis the two-particle-irreducible (2PI) formalism is investigated with several applications, particular emphasis on renormalizability. In the O(N) symmetric scalar quantu…

Broken symmetry phase solution of the phi^4 model at two-loop level of the Phi-derivable approximation
G. Fejos, Zs. Szep
The set of coupled equations for the self-consistent propagator and the field expectation value is solved numerically with high accuracy in Euclidean space at zero temperature and…

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…
