New soluble nonlinear models for scalar fields
C. A. Almeida, D. Bazeia, L. Losano +1
We extend a deformation prescription recently introduced and present some new soluble nonlinear problems for kinks and lumps. In particular, we show how to generate models which pr…
Nonclassical degree of states of single and bipartite systems
A. T. Avelar, B. Baseia, J. M. C. Malbouisson
We consider experimental routes to determine the nonclassical degree of states of a field mode. We adopt a distance-type criterium based on the Hilbert-Schmidt metric to quantify t…
Confinement in the 3-dimensional Gross-Neveu model
A. P. C. Malbouisson, J. M. C. Malbouisson, A. E. Santana +1
We consider the -components 3-dimensional massive Gross-Neveu model compactified in one spatial direction, the system being constrained to a slab of thickness . We derive a c…
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…
