Universality of entropy principle for a general diffeomorphism-covariant purely gravitational theory
Jie Jiang, Xiongjun Fang, Sijie Gao
Thermodynamics plays an important role in gravitational theories. It is a principle independent of the gravitational dynamics, and there is still no rigorous proof to show that it…
Consistency between dynamical and thermodynamical stabilities for charged self-gravitating perfect fluid
Wei Yang, Xiongjun Fang, Jiliang Jing
The entropy principle shows that, for self-gravitating perfect fluid, the Einstein field equations can be derived from the extrema of the total entropy, and the thermodynamical sta…
Gravitational wave cosmology I: high frequency approximation
Jared Fier, Xiongjun Fang, Bowen Li +3
In this paper, we systematically study gravitational waves (GWs) produced by remote compact astrophysical sources. To describe such GWs properly, we introduce three scales, $λ, \;…
Thermodynamical stability for perfect fluid
Xiongjun Fang, Xiaokai He, Jiliang Jing
According to maximum entropy principle, it has been proved that the gravitational field equations could be derived by the extrema of total entropy for perfect fluid, which implies…
