An effective field theory approach to monopolium
L. M. Abreu, M. de Montigny, P. P. A. Ouimet
In this work we investigate the interaction between spin-zero and spin-one monopoles by making use of an effective field theory based on two-body and four-body interaction parts. I…
Critical behaviour of an effective relativistic mean field model in the presence of magnetic background and boundaries
L. M. Abreu, E. S. Nery
In the present work we investigate the combined influence of magnetic background and boundaries on the thermodynamic properties of effective relativistic mean field models, like th…
Magnetic effects on spontaneous symmetry breaking/restoration in a toroidal topology
L. M. Abreu, C. A. Linhares, A. P. C. Malbouisson +1
We study temperature and finite-size effects on the spontaneous symmetry breaking/restoration for a scalar field model under the influence of an external magnetic field, at finite…
Finite-size effects on the phase diagram of difermion condensates in two-dimensional four-fermion interaction models
L. M. Abreu, A. P. C. Malbouisson, J. M. C. Malbouisson
We investigate finite-size effects on the phase structure of chiral and difermion condensates at finite temperature and density in the framework of the two-dimensional large- Na…
Finite-size effects on the phase structure of the Nambu-Jona-Lasinio model
L. M. Abreu, M. Gomes, A. J. da Silva
The Nambu-Jona-Lasinio (NJL) model is one of the most frequently used four-fermion models in the study of dynamical symmetry breaking. In particular, the NJL model is convenient fo…
