THERMODYNAMIC GEOMETRY AND CRITICAL BEHAVIOR OF BLACK HOLES
- Jianyong Shen, R. Cai, Bin Wang, R. Su

- 6 December 2005
Based on the observations that there exists an analogy between the Reissner–Nordstrom–Anti-de Sitter (RN–AdS) black holes and the van der Waals–Maxwell liquid-gas system, in which a correspondence of…
Signature of the Van der Waals like small-large charged AdS black hole phase transition in quasinormal modes

A bstractWe calculate the quasinormal modes of massless scalar perturbations around small and large four-dimensional Reissner-Nordstrom-Anti de Sitter (RN-AdS) black holes. We find a dramatic change…

Thermodynamics of an accelerated expanding universe
- Bin Wang, Y. Gong, E. Abdalla
- Physics
- 10 November 2005
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 relevant part of the…
Hawking radiation in a d-dimensional static spherically symmetric black hole surrounded by quintessence
- Songbai Chen, Bin Wang, R. Su
- Physics
- 14 January 2008
We present a solution of Einstein equations with quintessential matter surrounding a d-dimensional black hole, whose asymptotic structures are determined by the state of the quintessential matter. We…
Testing the interaction between dark energy and dark matter via latest observations
- Jian-hua He, Bin Wang, E. Abdalla
- Physics
- 17 December 2010
Cosmological analyses based on currently available observations are unable to rule out a sizeable coupling between dark energy and dark matter. However, the signature of the coupling is not easy to…
Holographic Superconductors with various condensates in Einstein-Gauss-Bonnet gravity
- Qiyuan Pan, Bin Wang, E. Papantonopoulos, J. Oliveira, A. B. Pavan
- Physics
- 13 December 2009
We study holographic superconductors in Einstein-Gauss-Bonnet gravity. We consider two particular backgrounds: a d-dimensional Gauss-Bonnet-AdS black hole and a Gauss-Bonnet-AdS soliton. We discuss…
Testing the interaction between dark energy and dark matter with Planck data
- A. Costa, Xiao-dong Xu, Bin Wang, Elisa G. M. Ferreira, E. Abdalla
- Physics
- 28 November 2013
Interacting Dark Energy and Dark Matter is used to go beyond the standard cosmology. We base our arguments on Planck data and conclude that an interaction is compatible with the observations and can…
Stability of Reissner-Nordström black hole in de Sitter background under charged scalar perturbation
- Zhi-ying Zhu, Shao-Jun Zhang, C. Pellicer, Bin Wang, E. Abdalla
- Physics
- 19 May 2014
We find a new instability in the four-dimensional Reissner-Nordstrom-de Sitter black holes against charged scalar perturbations with vanishing angular momentum, $l=0$. We show that such an…
