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, \;…
