Thermodynamics of Apparent Horizon in Brane World Scenario
Rong-Gen Cai, Li-Ming Cao
In this paper we discuss thermodynamics of apparent horizon of an -dimensional Friedmann-Robertson-Walker (FRW) universe embedded in an -dimensional AdS spacetime. By usi…
Unified First Law and Thermodynamics of Apparent Horizon in FRW Universe
Rong-Gen Cai, Li-Ming Cao
In this paper we revisit the relation between the Friedmann equations and the first law of thermodynamics. We find that the unified first law firstly proposed by Hayward to treat t…
New interpretation of matter-antimatter asymmetry based on branes and possible observational consequences
Rong-Gen Cai, Tong Li, Xue-Qian Li +1
Motivated by the AMS project, we assume that after the Big Bang or inflation epoch, antimatter was repelled onto one brane which is separated from our brane where all the observati…
Thermodynamic Behavior of Friedmann Equation at Apparent Horizon of FRW Universe
M. Akbar, Rong-Gen Cai
It is shown that the differential form of Friedmann equation of a FRW universe can be rewritten as a universal form at apparent horizon, where and are the…
Two 3-Branes in Randall-Sundrum Setup and Current Acceleration of the Universe
Anzhong Wang, Rong-Gen Cai, N. O. Santos
Five-dimensional spacetimes of two orbifold 3-branes are studied, by assuming that {\em the two 3-branes are spatially homogeneous, isotropic, and independent of time}, following t…
Cheng-Weyl Vector Field and its Cosmological Application
Hao Wei, Rong-Gen Cai
Weyl's idea on scale invariance was resurrected by Cheng in 1988. The requirement of local scale invariance leads to a completely new vector field, which we call the ``Cheng-Weyl v…
