规则磁黑洞周围的带电标量扰动

Charged scalar perturbations around a regular magnetic black hole

Yang Huang, Dao-Jun Liu

摘要:

研究了规则磁黑洞背景中的带电标量扰动。在这种情况下,带电标量扰动不会导致超辐射。通过仔细的时域分析,我们证明了标量场的电荷可以改变准正规频率的实部,但对准正规频率的虚部和后期尾部的行为影响不大。因此,规则磁性黑洞在带电标量场的线性扰动下可能是稳定的。

英文摘要:

We study charged scalar perturbations in the background of a regular magnetic black hole. In this case, the charged scalar perturbation does not result in superradiance. By using careful time-domain analysis, we show that the charge of scalar field can change the real part of quasinormal frequency, but has little impact on the imaginary part of quasinormal frequency and the behavior of the late-time tail. Therefore, the regular magnetic black hole may be stable under the perturbations of charged scalar field at the linear level.
