Finite-size effects on the phase transition in a four- and six-fermion interaction model
L. M. Abreu, F. C. Khanna, A. P. C. Malbouisson +2
We consider four- and six-fermion interacting models at finite temperature and density. We construct the corresponding free energies and investigate the appearance of first- and se…
Finite-size effects on the chiral phase diagram of four-fermion models in four dimensions
L. M. Abreu, A. P. C. Malbouisson, J. M. C. Malbouisson +1
We study the size dependence of the dynamical symmetry breaking in the four-dimensional Nambu-Jona-Lasinio model. We show that the presence of boundaries reduces the chiral breakin…
The Cangemi-Jackiw manifold in high dimensions and symplectic structure
L. M. Abreu, A. E. Santana, A. Ribeiro Filho
The notion of Poincare gauge manifold (), proposed in the context of an (1+1) gravitational theory by Cangemi and Jackiw (D. Cangemi and R. Jackiw, Ann. Phys. (N.Y.) 225 (1993)…
