Electrically Charged Non-Abelian Black String in Anti-de Sitter Space
G. Alencar, R. N. Costa Filho, I. Jardim +1
We construct a new family of static, electrically charged, cylindrically symmetric black-string solutions of four-dimensional Einstein--Yang--Mills theory with a negative cosmologi…
The End of the Road for Bulk Fields in Warped Randall-Sundrum Braneworlds
G. Alencar, R. S. Almeida, R. N. Costa Filho +2
In this manuscript we generalize Ref. [1] and derive a complete set of local consistency conditions for bulk fields in braneworld scenarios with an arbitrary number of dimensions.…
A New Cloud of Strings
G. Alencar, R. R. Landim, R. N. Costa Filho
In this work, we present a generalization of the cloud of strings model originally proposed by Letelier, by introducing a magnetic-like component, , in addition to the ele…
Neutrino mass generation via the inverse seesaw mechanism in a gauge extension
Higo Barros Nogueira, Job Saraiva Furtado Neto, Raimundo Nogueira da Costa Filho +1
We present anomaly-free solutions suitable for an inverse seesaw realization within a extension. Implementing such a mechanism, in a phenomenologically viable way, req…
Traversable Wormholes Sourced by Dark Matter in Loop Quantum Cosmology
Marcos V. de S. Silva, G. Alencar, R. N. Costa Filho +2
In this work, we investigate the existence of wormholes within the framework of Loop Quantum Cosmology, using isotropic dark matter as the source. We analyze three distinct density…
