Effective dynamics of Janis-Newman-Winicour spacetime
Faqiang Yuan, Shengzhi Li, Zhen Li +1
The effective dynamics of the Janis-Newman-Winicour spacetime inspired by loop quantum gravity is studied. Two different schemes are considered to regularize the Hamiltonian constr…
Energy extraction via Comisso-Asenjo mechanism from rotating hairy black hole
Zhen Li, Faqiang Yuan
It was demonstrated by Comisso and Asenjo that the magnetic reconnection in the ergosphere is a promising mechanism to extract energy from the rotating Kerr black hole. In this wor…
Energy extraction from rotating regular black hole via Comisso-Asenjo mechanism
Zhen Li, Xiao-Kan Guo, Faqiang Yuan
Recently, it has been demonstrated by Comisso and Asenjo that magnetic reconnection processes in the ergosphere of a Kerr black hole can provide us with a promising mechanism for e…
Scalar Perturbation Around Rotating Regular Black Hole: Superradiance Instability and Quasinormal Modes
Zhen Li
Black holes provide a natural laboratory to study particle physics and astrophysics. When black holes are surrounded by matter fields, there will be plenty of phenomena which can h…
Weak cosmic censorship conjecture in higher-dimensional black holes with nonlinear electrodynamic sources
Zhen Li, Yunjiao Gao, Xiao-Kan Guo
The new version of the gedanken experiments proposed by Sorce and Wald are designed to test the validity of the weak cosmic censorship conjecture (WCCC) by overspinning or overchar…
