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…

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…

Are regular black holes from pure gravity classified within the same thermodynamical topology?
Sheng-Wei Wang, Shan-Ping Wu, Shao-Wen Wei
Regular black holes, which avoid the essential center singularities, can be constructed through various methods, including nonlinear electrodynamics and quantum corrections. Recent…
