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…

Observational Constraints on Varying-alpha Domain Walls
P. P. Avelino, L. Sousa
We consider the possibility that current hints of spatial variations of the fine structure constant at high redshift, based on VLT/UVES and Keck/HIRES observations, could be caused…

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…
