Abstract

We investigate the perturbation of the scalar field as well as the electromagnetic field over a sort of regular black holes which are characterized by the sub-Planckian curvature and the Minkowskian core. Specifically, we compute the quasinormal modes (QNMs) by employing the pseudo-spectral method. The outburst of overtones is manifestly observed in the QNMs of these regular black holes, which can be attributed to the deviation of the Schwarzschild black hole by quantum effects of gravity. Furthermore, the QNMs under the perturbation of electromagnetic field exhibit smaller real and imaginary parts than those under scalar field perturbation. By comparing the QNMs of the regular black hole featured by Minkowskian core with those of Bardeen black hole featured by de Sitter core, we find they may be an effective tool to distinguish these BHs.

具有亚普朗克曲率和明科夫斯基内核的规则黑洞的准正常模式

我们研究了一种规则黑洞上的标量场和电磁场的扰动，这种黑洞的特征是亚普朗克曲率和明科夫斯基内核。具体来说，我们采用伪谱法计算了准正常模式（QNMs）。在这些规则黑洞的 QNMs 中可以明显观察到泛音的爆发，这可以归因于施瓦兹柴尔德黑洞在引力量子效应下的偏离。此外，电磁场扰动下的 QNMs 的实部和虚部都小于标量场扰动下的 QNMs。通过比较以明科夫斯基内核为特征的规则黑洞和以德西特内核为特征的巴丁黑洞的QNMs，我们发现它们可能是区分这些黑洞的有效工具。
