First law and Smarr formula of black hole mechanics in nonlinear gauge theories
Yuan Zhang, Sijie Gao
Motivated by the fact that Bardeen black holes do not satisfy the usual first law and Smarr formula, we derive a generalized first law from the Lagrangian of nonlinear gauge field…
Mass Dependence of the Entropy Product and Sum
Yuan Zhang, Sijie Gao
For black holes with multiple horizons, the area product of all horizons has been proven to be mass independent in many cases. Counterexamples were also found in some occasions. In…
Testing cosmic censorship conjecture near extremal black holes with cosmological constants
Yuan Zhang, Sijie Gao
It has been shown previously that an extremal Reissner-Nordström or an extremal Kerr black hole cannot be overcharged or overspun by a test particle if radiative and self-force eff…
Destroying extremal Kerr-Newman black holes with test particles
Sijie Gao, Yuan Zhang
It has been shown that a nearly extremal black hole can be overcharged or overspun by a test particle if radiative and self-force effects are neglected, indicating that the cosmic…
