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…
The universal topological charge of black hole photon spheres in higher dimensions
Jun-Lei Chen, Shan-Ping Wu, Shao-Wen Wei

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…
Precession of spherical orbits for the spacetime without symmetry induced by NUT charge
Xiang-Cheng Meng, Shan-Ping Wu, Shao-Wen Wei
Astrophysical evidence has hinted at the existence of a nonzero NUT charge, which breaks the symmetry of spacetime and induces novel features in geodesics. In this w…
Universal exponents of black hole phase transition at zero-temperature limit
