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…
Critical behaviour of the compactified theory
L. M. Abreu, C. de Calan, A. P. C. Malbouisson +2
We investigate the critical behaviour of the -component Euclidean model at leading order in -expansion. We consider it in three situations: confined between…
Halperin-Lubensky-Ma effect in type-I superconducting films
L. M. Abreu, C. de Calan, A. P. C. Malbouisson
In this note we employ concurrently techniques of generalized -functions and compactification methods introduced in previous publications, to study the Halperin-Lubensky-Ma t…
Large-N transition temperature for superconducting films in a magnetic field
L. M. Abreu, A. P. C. Malbouisson, J. M. C. Malbouisson +1
We consider the -component Ginzburg-Landau model in the large limit, the system being embedded in an external constant magnetic field and confined between two parallel plane…
