Holography, UV/IR Relation, Causal Entropy Bound and Dark Energy
Rong-Gen Cai, Bin Hu, Yi Zhang
The constraint on the total energy in a given spatial region is given from holography by the mass of a black hole which just fits in that region, which leads to an UV/IR relation:…
Shear Viscosity from Effective Couplings of Gravitons
Rong-Gen Cai, Zhang-Yu Nie, Ya-Wen Sun
We calculate the shear viscosity of field theories with gravity duals using Kubo-formula by calculating the Green function of dual transverse gravitons and confirm that the value o…
Generalized Vaidya Spacetime in Lovelock Gravity and Thermodynamics on Apparent Horizon
Rong-Gen Cai, Li-Ming Cao, Ya-Peng Hu +1
We present a kind of generalized Vaidya solutions in a generic Lovelock gravity. This solution generalizes the simple case in Gauss-Bonnet gravity reported recently by some authors…
Hawking Radiation of Apparent Horizon in a FRW Universe
Rong-Gen Cai, Li-Ming Cao, Ya-Peng Hu
Hawking radiation is an important quantum phenomenon of black hole, which is closely related to the existence of event horizon of black hole. The cosmological event horizon of de S…
Corrected Entropy-Area Relation and Modified Friedmann Equations
Rong-Gen Cai, Li-Ming Cao, Ya-Peng Hu
Applying Clausius relation, , to apparent horizon of a FRW universe with any spatial curvature, and assuming that the apparent horizon has temperature $T=1/(2π\tilde {r}_A)…
Shear Viscosity from AdS Born-Infeld Black Holes
Rong-Gen Cai, Ya-Wen Sun
We calculate the shear viscosity in the frame of AdS/CFT correspondence for the field theory with a gravity dual of Einstein-Born-Infeld gravity. We find that the ratio of is…
