Journal ArticleDOI
Gauss-Bonnet black holes in AdS spaces
Rong-Gen Cai,Rong-Gen Cai +1 more
TL;DR: In this article, the authors studied the thermodynamic properties and phase structures of topological black holes in Einstein theory with a Gauss-Bonnet term and a negative cosmological constant.
Journal ArticleDOI
A new model of agegraphic dark energy
Hao Wei,Rong-Gen Cai +1 more
TL;DR: Cai et al. as mentioned in this paper proposed a new model of agegraphic dark energy based on the Karolyhazy relation, where the time scale is chosen to be the conformal time eta of the Friedmann-Robertson-Walker (FRW) universe.
Journal ArticleDOI
A dark energy model characterized by the age of the Universe
TL;DR: In this article, the age of the universe is introduced as the length measure and a dark energy model is proposed based on the energy density of quantum fluctuations of space-time, which is consistent with astronomical data if the unique numerical parameter is taken to be a number of order one.
Journal ArticleDOI
Thermodynamic behavior of the Friedmann equation at the apparent horizon of the FRW universe
M. Akbar,Rong-Gen Cai +1 more
TL;DR: In this paper, it was shown that the Friedmann equation of a FRW universe can be rewritten as the first law of thermodynamics, where the entropy of the apparent horizon is given by the thermodynamic identity of the universe.
Journal ArticleDOI
Friedmann equations of FRW universe in scalar–tensor gravity, f(R) gravity and first law of thermodynamics
M. Akbar,Rong-Gen Cai +1 more
TL;DR: Cai et al. as discussed by the authors derived Friedmann equations for the FRW universe with any spatial curvature using the entropy formula for the static spherically symmetric black holes in Gauss-Bonnet gravity and Lovelock gravity.
