Braneworld cosmology in gravity
J. J. Ramos, J. E. G. Silva
This work investigates the cosmology of a thick brane within the context of gravity, an extension of symmetric teleparallelism. Using a five-dimensional Friedmann-L…
Testing a cosmological teleparallel modified f(T) model with parametric H(z)
Adriel O. Aquino, J. E. G. Silva
We study the late-time cosmological expansion of a modified teleparallel gravity model. This modified gravitational lagrangian yields a cosmological constant term along with power-…
Black string solutions in Lifshitz spacetime
L. A. Lessa, J. E. G. Silva, J. Furtado
In this paper we study black string solutions considering the Lifshitz anisotropic scaling. We have shown that a new class of asymptotically Lifshitz solutions can be generated by…
Braneworlds in Warped Einsteinian Cubic Gravity
L. A. Lessa, R. V. Maluf, J. E. G. Silva +1
Einstenian cubic gravity (ECG) is a modified theory of gravity constructed with cubic contractions of the curvature tensor. This theory has the remarkable feature of having the sam…
Einstein-Bumblebee-Dilaton black hole in Lifshitz spacetimes
L. A. Lessa, J. E. G. Silva
We investigate the critical behavior of Lifshitz black holes in Einstein-dilaton gravity in the context of spontaneous Lorentz symmetry breaking. Considering the effects of both th…
Traversable wormhole solution with a background Kalb-Ramond field
L. A. Lessa, R. Oliveira, J. E. G. Silva +1
We obtain a static spherically symmetric wormhole solution due to the vacuum expectation value (VEV) of a Kalb-Ramond field. The Kalb-Ramond VEV is a background tensor field which…
