Effective Pressure of the FRW Universe
Shi-Bei Kong
In this paper, we study the effective pressure of the -dimensional FRW(Friedmann-Robertson-Walker) universe in Einstein gravity, Gauss-Bonnet gravity, and Lovelock gravity. The…
Equation of the Perfect Fluid in the FRW Universe
Shi-Bei Kong, Ying Wang, Yu-Ke Wang
In this paper, we study the equation of state and its properties of the perfect fluid in the -dimensional FRW universe under Einstein gravity, Gauss-Bonnet gravity and Lovelock…
Heat Capacity and the Violation of Scaling Laws in Gravitational System
Shi-Bei Kong
In this paper, we examine the scaling laws in gravitational system from the perspective of free energy landscape and the scaling hypothesis. It has been found that for some special…
