Thermodynamics of an accelerated expanding universe
Bin Wang, Yungui Gong, Elcio Abdalla
We investigate the laws of thermodynamics in an accelerating universe driven by dark energy with a time-dependent equation of state. In the case we consider that the physically rel…
Constraints on the interacting holographic dark energy model
Bin Wang, Chi-Yong Lin, Elcio Abdalla
We examined the interacting holographic dark energy model in a universe with spatial curvature. Using the near-flatness condition and requiring that the universe is experiencing an…
Scalar field evolution in Gauss-Bonnet black holes
E. Abdalla, R. A. Konoplya, C. Molina
It is presented a thorough analysis of scalar perturbations in the background of Gauss-Bonnet, Gauss-Bonnet-de Sitter and Gauss-Bonnet-anti-de Sitter black hole spacetimes. The per…
Classical Non-Local conserved charges in String Theory
Elcio Abdalla, Antonio Lima-Santos
We construct a conserved non local charge in string theory.
Transition of the dark energy equation of state in an interacting holographic dark energy model
Bin Wang, Yungui Gong, Elcio Abdalla
A model of holographic dark energy with an interaction with matter fields has been investigated. Choosing the future event horizon as an IR cutoff, we have shown that the ratio of…
Scalar field perturbations of the Schwarzschild black hole in the Gödel Universe
R. A. Konoplya, Elcio Abdalla
We investigate the scalar field perturbations of the 4+1-dimensional Schwarzschild black hole immersed in a Gödel Universe, described by the Gimon-Hashimoto solution.This may model…
