Counterterm resummation for 2PI-approximation in constant background
A. Patkos, Zs. Szep
Explicit counterterm construction is presented in a symmetry breaking background for the 2PI effective action of the self-interacting one-component scalar field including skeleton…

Renormalisability of the 2PI-Hartree approximation of multicomponent scalar models in the broken symmetry phase
G. Fejos, A. Patkos, Zs. Szep
Non-perturbative renormalisation of a general class of scalar field theories is performed at the Hartree level truncation of the 2PI effective action in the broken symmetry regime.…
