Exact algebraic separation of the gravitoelectromagnetic perturbations of Kerr-Newman-(anti-)de Sitter black holes
Jun-Kun Zhao
We obtain an explicit separation of the coupled gravitational and electromagnetic radiative equations on nonextremal Kerr--Newman--(anti-)de Sitter black holes with nonzero charge…
Time evolutions of scalar field perturbations in -dimensional Reissner-Nordström Anti-de Sitter black holes
Ran Li, Hongbao Zhang, Junkun Zhao
Reissner-Nordström Anti-de Sitter (RNAdS) black holes are unstable against the charged scalar field perturbations due to the well-known superradiance phenomenon. We present the tim…
Time domain analysis of superradiant instability for the charged stringy black hole-mirror system
Ran Li, Yu Tian, Hongbao Zhang +1
It has been proved that the charged stringy black holes are stable under the perturbations of massive charged scalar fields. However, superradiant instability can be generated by a…
Numerical study of superradiant instability for charged stringy black hole-mirror system
Ran Li, Junkun Zhao
We numerically study the superradiant instability of charged massless scalar field in the background of charged stringy black hole with mirror-like boundary condition. We compare t…
Superradiant instability of D-dimensional Reissner-Nordström black hole mirror system
Ran Li, Zhaojun Kun, Yanming Zhang
We analytically study the superradiant instability of a charged massless scalar field in the background of D-dimensional Reissner-Nordström (RN) black hole caused by the mirror's b…
Superradiant instability of the charged scalar field in stringy black hole mirror system
Ran Li, Junkun Zhao
It has been shown that the mass of the scalar field in the charged stringy black hole is never able to generate a potential well outside the event horizon to trap the superradiant…
