Charged scalar and Dirac perturbations on a global monopole Reissner-Nordström-de Sitter black hole: quasinormal modes and strong cosmic censorship

Peiyang Li, Mengjie Wang, Jiliang Jing

We study perturbations of charged scalar and Dirac fields around Reissner-Nordström-de Sitter black holes with a global monopole. To this end, we first derive the equations of mot…

Charged Dirac perturbations on Reissner-Nordström black holes in a cavity: quasinormal modes with Robin boundary conditions

Jia Liu, Mengjie Wang, Zishuo Wang +3

We investigate charged Dirac quasinormal spectra on Reissner-Nordström black holes in a mirror-like cavity. For this purpose, we first derive charged Dirac equations, and \textit{…

Harvesting entanglement from the Lorentz-violating quantum field vacuum in a dipolar Bose-Einstein condensate

Zehua Tian, Weiping Yao, Xiaobao Liu +3

We theoretically propose an experimentally viable scheme to explore the transfer of nonclassical correlations from a dipolar Bose-Einstein condensate (BEC) to a pair of impurities…

Complete quasinormal modes of Type-D black holes

Changkai Chen, Jiliang Jing, Zhoujian Cao +1

Quasinormal mode (QNM) spectra of black holes exhibit two open problems [Conf. Proc. C 0405132, 145 (2004); CQG 26, 163001 (2009)]: (i) the discontinuity in highly damped QNMs betw…

Stationary scalar clouds around a rotating BTZ-like black hole in the Einstein-bumblebee gravity

Fangli Quan, Fengjiao Li, Qiyuan Pan +2

We have studied stationary clouds of massive scalar fields around a rotating BTZ-like black hole in the Einstein-bumblebee gravity, by imposing the Robin type boundary conditions a…
