We compute the corrections of next to leading order in the 1/N expansion to the effective potential of a system described by a Ginzburg-Landau model with N components and quartic interaction, in the case of spontaneous symmetry breaking. The method we apply allows to generalize in a simple way the so-called self-consistent screened approximation (SCSA).

Abstract
We compute the corrections of next to leading order in the 1/N expansion to the effective potential of a system described by a Ginzburg-Landau model with N components and quartic interaction, in the case of spontaneous symmetry breaking. The method we apply allows to generalize in a simple way the so-called self-consistent screened approximation (SCSA).File in questo prodotto:
