Scalar and tensor gauge field localization on deformed thick branes
W. T. Cruz, M. O. Tahim, C. A. S. Almeida
We make an analysis about several aspects of localization of a scalar field and a Kalb-Ramond gauge field in a specific four dimensional AdS membrane embedded in a five dimensional…
Fermion localization and resonances on two-field thick branes
C. A. S. Almeida, M. M. Ferreira, A. R. Gomes +1
We consider -dimensional branes constructed with two scalar fields and coupled to a Dirac spinor field by means of a general Yukawa coupling. The equation of motion…
Tensor gauge field localization in branes
M. O. Tahim, W. T. Cruz, C. A. S. Almeida
In this work we study localization of a Kalb-Ramond tensorial gauge field on a membrane described by real scalar fields. The membrane is embedded in an AdS-type five dimensional bu…
Nonminimal Maxwell-Chern-Simons-O(3)-sigma vortices: asymmetric potential case
M. S. Cunha, R. R. Landim, C. A. S. Almeida
In this work we study a nonlinear gauged O(3)-sigma model with both minimal and nonminimal coupling in the covariant derivative. Using an asymmetric scalar potential, the model is…
