Symmetry breaking patterns for two coupled complex scalar fields at finite temperature and in an external magnetic field
R. L. S. Farias, Rudnei O. Ramos, Dérick S. Rosa
A model of two coupled complex scalar fields is studied at finite temperature and under an external magnetic field. The results are obtained in the context of the nonperturbative m…

Reliability of the optimized perturbation theory in the 0-dimensional scalar field model
Dérick S. Rosa, R. L. S. Farias, Rudnei O. Ramos
We address the reliability of the Optimized Perturbation Theory (OPT) in the context of the 0-dimensional scalar field model. The effective potential, the self-energy and th…
