We study the quasinormal modes of the charged scalar perturbations in the background of the Einstein-Maxwell-aether black hole through three methods (WKB method, continued fraction method, generalized eigenvalue method). Then we propose the specific treatment for the generalized effective potential with ω-dependence and the complete procedure of transforming calculation continued fraction method into finding the zero point of the corresponding complex function numerically. These methods are valid because the results from different methods are consistent. We also investigate the allowed region of the second kind aether black hole among the system parameters (c13,c14,Q). Finally we show the existence of quasiresonances of massive perturbation for Einstein-Maxwell-aether black hole even with large aether parameter.

爱因斯坦-麦克斯韦-以太黑洞的准正态模式

我们通过三种方法(WKB法、连分数法、广义特征值法)研究了爱因斯坦-麦克斯韦-以太黑洞背景下带电标量扰动的准常态模式。然后我们提出了针对广义有效势的具体处理方法ω——将计算连分数法转化为数值求相应复函数零点的依赖关系和完整过程。这些方法是有效的,因为不同方法的结果是一致的。我们还研究了系统参数中第二类以太黑洞的允许区域(C13,C14,)。最后,我们证明了即使在大以太参数的情况下,爱因斯坦-麦克斯韦-以太黑洞也存在大规模摄动的准共振。
