Generating mass and topological terms to the antisymmetric tensor matter field by Higgs mechanism
L. Gonzaga Filho, M. S. Cunha, C. A. S. Almeida +1
The interaction between the complex antisymmetric tensor matter field and a scalar field is constructed. We analyze the Higgs mechanism and show the generation of mass and topologi…
Generalized axion-photon couplings and dual descriptions on brane-worlds
M. O. Tahim, C. A. S. Almeida
In this work we obtain topological and dual theories on brane-worlds in several dimensions. Our brane is a solitonic-like hypersurface embedded in a space-time with a specific dime…
Topological Gravity, the Hierarchy Problem and Axion Physics
Carlos Alberto Santos Almeida, Makarius Oliveira Tahim
In the last years higher dimensional physics has won importance. Despite the Superstrings, higher dimensional effects, in measurable scales of energy (some TeV), became only possib…
Dualization of non-Abelian model
C. A. S. Almeida, R. R. Landim, D. M. Medeiros
In this work we show a dualization process of a non-Abelian model with an antisymmetric tensor gauge field in a three-dimensional space-time. We have constructed a non-Abelian gaug…
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…
Nonabelian topological mass mechanism for a three-dimensional 2-form field
D. M. Medeiros, R. R. Landim, C. A. S. Almeida
Starting from a recently proposed abelian topological model in (2+1) dimensions, we use the method of the consistent deformations to prove that a topologically massive model involv…
