Gauss-Bonnet black holes in AdS spaces
- R. Cai
- Physics
- 18 September 2001
We study the thermodynamic properties and phase structures of topological black holes in Einstein theory with a Gauss-Bonnet term and a negative cosmological constant. The event horizon of these…
First law of thermodynamics and Friedmann equations of Friedmann-Robertson-Walker universe
- R. Cai, Sang Pyo Kim
- Physics
- 8 January 2005
Applying the first law of thermodynamics to the apparent horizon of a Friedmann-Robertson-Walker universe and assuming the geometric entropy given by a quarter of the apparent horizon area, we derive…
Action growth for AdS black holes
- R. Cai, Shan-Ming Ruan, Shao-Jiang Wang, Runqiu Yang, Rong-Hui Peng
- Physics
- 23 June 2016
A bstractRecently a Complexity-Action (CA) duality conjecture has been proposed, which relates the quantum complexity of a holographic boundary state to the action of a Wheeler-DeWitt (WDW) patch in…
Thermodynamics of Black Holes in Massive Gravity
- R. Cai, Yapeng Hu, Qiaoyin Pan, Yun-long Zhang
- Physics
- 8 September 2014
We present a class of charged black hole solutions in an (n + 2)-dimensional massive gravity with a negative cosmological constant, and study thermodynamics and phase structure of the black hole…
Estimating cosmological parameters by the simulated data of gravitational waves from the Einstein Telescope
We investigate the constraint ability of the gravitational wave (GW) as the standard siren on the cosmological parameters by using the third-generation gravitational wave detector: the Einstein…
P-V criticality in the extended phase space of Gauss-Bonnet black holes in AdS space
- R. Cai, Li-ming Cao, L. Li, Runqiu Yang
- Physics
- 26 June 2013
A bstractWe study the P − V criticality and phase transition in the extended phase space of charged Gauss-Bonnet black holes in anti-de Sitter space, where the cosmological constant appears as a…
Emergence of space and spacetime dynamics of Friedmann-Robertson-Walker universe
- R. Cai
- Physics
- 3 July 2012
A bstractIn a recent paper [arXiv:1206.4916] by T. Padmanabhan, it was argued that our universe provides an ideal setup to stress the issue that cosmic space is emergent as cosmic time progresses and…
Unified first law and the thermodynamics of the apparent horizon in the FRW universe
- R. Cai, Li-ming Cao
- Physics
- 14 November 2006
In this paper we revisit the relation between the Friedmann equations and the first law of thermodynamics. We find that the unified first law first proposed by Hayward to treat the outertrapping…
