Classical double copy of black strings in an Anti-de Sitter background
G. Alencar, C. R. Muniz, M. S. Oliveira
We study the classical double copy for static black string solutions in an Anti--de Sitter (AdS) background. By casting the black string metric into Kerr--Schild form over a cylind…

The dark sector of the Universe as a scalar field in Horndeski Gravity
M. S. Oliveira, F. A. Brito, J. A. V. Campos
In the present work, we study a subclass of Horndeski gravity characterized by a non-minimal derivative coupling between a scalar field and the Einstein tensor, as a possible alter…

Hořava-Lifshitz cosmological models in noncommutative space-times
E. M. C. Abreu, A. C. R. Mendes, G. Oliveira-Neto +3
In this work, we will analyze a noncommutative (NC) version of the Friedmann-Robert-Walker cosmological models within the gravitational Hořava-Lifshitz theory. The matter content o…
