Gravity localization in sine-Gordon braneworlds
W. T. Cruz, R. V. Maluf, L. J. S. Sousa +1
In this work we study two types of five-dimensional braneworld models given by sine-Gordon potentials. In both scenarios, the thick brane is generated by a real scalar field couple…
Vector and fermion fields on a bouncing brane with a decreasing warp factor in a string-like defect
L. J. S. Sousa, C. A. S. Silva, D. M. Dantas +1
In a recent work, a model has been proposed where a brane is made of a scalar field with bounce-type configurations and embedded in a bulk with a string-like metric. This model pro…
A 6D standing-wave Braneworld with normal matter as source
L. J. S. Sousa, W. T. Cruz, C. A. S. Almeida
A six dimensional standing-wave braneworld model has been constructed. It consists in an anisotropic 4-brane generated by standing gravitational waves whose source is normal matter…
Graviton resonances on two-field thick branes
W. T. Cruz, L. J. S. Sousa, R. V. Maluf +1
This work presents new results about the graviton massive spectrum in two-field thick branes. Analyzing the massive spectra with a relative probability method we have firstly showe…
A 6D standing wave Braneworld
L. J. S. Sousa, J. E. G. Silva, C. A. S. Almeida
We constructed a six-dimensional version of the standing wave model with an anisotropic 4-brane generated by a phantom-like scalar field. The model represents a braneworld where th…
Tensor gauge field localization on a string-like defect
L. J. S. Sousa, W. T. Cruz, C. A. S. Almeida
This work is devoted to the study of tensor gauge fields on a string-like defect in six dimensions. This model is very successful in localizing fields of various spins only by grav…
