de Sitter Entropy from a lower dimensional black hole
Cesar Arias, Rodrigo Aros, Nelson Zamorano
An alternative method to compute the entropy of de Sitter spacetime for dimensions higher than or equal to five is presented. It is shown that de Sitter entropy may be obtained fro…
Analogue black hole in magnetohydrodynamics
Felipe A. Asenjo, Nelson Zamorano
We consider an irrotational plasma fluid evolving under the effect of a background magnetic field. The magnetohydrodynamic formalism is used to describe the electromagnetic waves a…
Kerr-Schild Method and Geodesic Structure in Codimension-2 Brane Black Holes
Bertha Cuadros-Melgar, Susana Aguilar, Nelson Zamorano
We consider the black hole solutions of five-dimensional gravity with a Gauss-Bonnet term in the bulk and an induced gravity term on a 2-brane of codimension-2. Applying the Kerr-S…
Compactification in first order gravity
Rodrigo Aros, Mauricio Romo, Nelson Zamorano
The Kaluza-Klein compactification process is applied in five dimensions to CS gravity, for the anti-de Sitter and Poincaré groups, using the first order formalism. In this context…
Conformal Gravity from AdS/CFT mechanism
Rodrigo Aros, Mauricio Romo, Nelson Zamorano
We explicitly calculate the induced gravity theory at the boundary of an asymptotically Anti-de Sitter five dimensional Einstein gravity. We also display the action that encodes th…
A Wormhole at the core of an infinite cosmic string
Rodrigo M Aros, Nelson Zamorano
We study a solution of Einstein's equations that describes a straight cosmic string with a variable angular deficit, starting with a deficit at the core. We show that the coo…
