Bumblebee field in a Topological Framework
L. P. Colatto, A. L. A. Penna, W. C. Santos
A vector field coming from spontaneous Lorentz violation mechanism, namely Bumblebee model is analysed in a topological framework in a Minkowski space-time. Taking a $(1+2…
A chargeless complex vector matter field in supersymmetric scenario
L. P. Colatto, A. L. A. Penna
In this paper we construct and study a formulation of a chargeless complex vector matter field in a supersymmetric framework. To this aim we combine two no-chiral scalar superfield…
Spontaneous Lorentz symmetry violation and topological defects for the Chern-Simons matter vector field
L. P. Colatto, A. L. A. Penna, W. C. Santos
The study of topological defects occurring in vector and tensor fields is an intriguing subject and little explored in the literature. In this article, we analyze the topological d…
Noncommutative geometry induced by spin effects
L. P. Colatto, A. L. A. Penna, W. C. Santos
In this paper we study the nonlocal effects of noncommutative spacetime on simple physical systems. Our main point is the assumption that the noncommutative effects are consequence…
Charged Tensor Matter Fields and Lorentz Symmetry Violation via Spontaneous Symmetry Breaking
L. P. Colatto, A. L. A. Penna, W. C. Santos
We consider a model with a charged vector field along with a Cremmer-Scherk-Kalb-Ramond (CSKR) matter field coupled to a U(1) gauge potential. We obtain a natural Lorentz symmetry…
On Finite Matrix Bi-Dimensional Formulation of Classical Field Models
L. P. Colatto, A. L. A. Penna, C. M. M. Polito
We introduce a basis for a bi-dimensional finite matrix calculus and a bi-dimensional finite matrix action principle. As an application, we analyze scalar and spinorial fields in $…
