规则黑洞的引力电磁微扰与准纳米数

Gravito-Electromagnetic Perturbations and QNMs of Regular Black Holes

Kun Meng, Shao-Jun Zhang

摘要:

在爱因斯坦引力与非线性电磁场耦合的框架下,我们研究了磁性规则黑洞的引力电磁微扰。通过将奇宇称的引力微扰与偶宇称的电磁微扰耦合,得到了微扰的主方程。作为应用,我们应用主方程数值求解了三类规则黑洞的准正规模。结果表明,规则黑洞的准数矩与理论参数和黑洞的磁荷密切相关,与Reissner-Nordström黑洞的准数矩有很大不同.这些结果的稳定性,这些规则的黑洞的迹象进行了详细讨论。

英文摘要:

In the framework of Einstein's gravity coupled to nonlinear electromagnetic fields, we study gravito-electromagnetic perturbations of magnetic regular black holes. The master equations of perturbations are obtained through Chandrasekhar's procedure, in which gravitational perturbations with odd-parity are coupled to the electromagnetic perturbations with even-parity. As an application, we apply the master equations to obtain quasinormal modes (QNMs) for three types of regular black holes by using numerical method. Results show that QNMs of regular black holes depends significantly on the parameters of the theory and the magnetic charge of the black holes and are very different from that of the Reissner-Nordström black hole. Indications of these results on the stability of these regular black holes are discussed in detail.
