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
Shao-Wen Wei, Shan-Ping Wu, Yu-Peng Zhang +1
In this work, we investigate the universal thermodynamic characteristics of black hole phase transitions at the zero-temperature limit. Our results reveal that, far below the criti…
Extended thermodynamical topology of black hole
Shan-Ping Wu, Si-Jiang Yang, Shao-Wen Wei
Thermodynamical topology has emerged as a powerful framework for classifying the thermodynamical behavior of black holes. Three distinct yet complementary topological invariants ha…
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…
Generalized Free Energy Landscapes from Iyer-Wald Formalism
Shan-Ping Wu, Yu-Xiao Liu, Shao-Wen Wei
The generalized free energy landscape plays a pivotal role in understanding black hole thermodynamics and phase transitions. In general relativity, one can directly derive the gene…
