Black Hole Entropy Beyond the Wald Term in Nonminimally Coupled Gravity: A Covariant Phase Space Decomposition
Jia-Zhou Liu, Shan-Ping Wu, Shao-Wen Wei +1
We study the entropy of static, spherically symmetric black holes in diffeomorphism-invariant theories with nonminimal matter--curvature couplings, using the covariant phase space…
Holographic complexity of de-Sitter black holes
Chaoxi Fang, Jiayue Yang, Shao-Wen Wei +2
We investigate holographic complexity within the Schwarzschild-de Sitter (SdS) black hole spacetime. Two distinct de Sitter holography prescriptions are examined: the static patch…
Topology of black hole thermodynamics: A brief review
Shao-Wen Wei, Yu-Xiao Liu
Recent explorations of topological aspects in black hole thermodynamics have achieved unprecedented progress. By utilizing topological numbers, different black hole systems can be…
Topologically equivalent yet radiatively distinct orbits in EMRI system
Chao-Hui Wang, Shao-Wen Wei, Tao Zhu +1
Multiple potential wells for massive test particles, allowing distinct families of bound orbits to coexist, are a characteristic feature of certain exotic compact objects beyond ge…
Gravitational equal-area law and critical phenomena of cuspy black hole shadow
Shao-Wen Wei, Chao-Hui Wang, Yu-Peng Zhang +2
The formation of a cusp on a black hole shadow is a striking signature of physics beyond the Kerr paradigm. We demonstrate that this morphological change fundamentally alters the s…
Deciphering black hole phase transitions through photon spheres
Si-Jiang Yang, Shan-Ping Wu, Shao-Wen Wei +1
Black hole thermodynamics is a crucial and foundational aspect of black hole physics, yet its observational verification remains exceptionally challenging. The photon sphere of a b…
