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…
Topological perspective on bulk boundary thermodynamic equivalence
Si-Jiang Yang, Shan-Ping Wu, Shao-Wen Wei +1
We establish an exact duality between the extended thermodynamics of five-dimensional charged Gauss-Bonnet AdS black holes and the thermodynamic framework of the dual boundary conf…
Exact Black Hole Solutions in Bumblebee Gravity with Lightlike or Spacelike VEVS
Jia-Zhou Liu, Shan-Ping Wu, Shao-Wen Wei +1
Motivated by recent developments in Lorentz-violating theories of gravity, we obtain new black hole solutions within the framework of bumblebee gravity, where the bumblebee vector…
Gravitational partition function under volume constraints
Shan-Ping Wu, Peng Cheng, Shao-Wen Wei
The Euclidean action provides a bridge between gravitational thermodynamics and the partition function. In this work, we further investigate the gravitational partition function un…
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…
Exact black hole solutions in gravity with a background Kalb-Ramond field
Jia-Zhou Liu, Shan-Ping Wu, Shao-Wen Wei +1
In this work, we derive exact solutions for four-dimensional static spherically symmetric black holes and three-dimensional rotating black holes within a Lorentz-violating gravity…
