Quantum Effective Dynamics of Papapetrou Spacetime
Xiaokan Guo, Faqiang Yuan
In this paper, we investigate the quantum effective dynamics of Papapetrou spacetime by using methods from loop quantum gravity. The Papapetrou spacetime is an extension of the Sch…

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…
