Charged Black Holes in New Massive GravityJul 25 2010Nov 06 2010We construct charged black hole solutions to three-dimensional New Massive Gravity (NMG), by adding electromagnetic Maxwell and Chern-Simons actions. We find charged black holes in the form of warped AdS_3 and "log" solutions in specific critical point. ... More
Generalized second law of thermodynamics in Gauss-Bonnet braneworldNov 27 2008Jul 25 2009We investigate the validity the generalized second law of thermodynamics in a general braneworld model with curvature correction terms on the brane and in the bulk, respectively. Employing the derived entropy expression associated with the apparent horizon, ... More
