AI总结:

研究具有 Minkowski 核心与亚普朗克曲率的正则黑洞 QNMs,发现其泛音爆发可揭示近视界量子引力修正并区分黑洞模型。

摘要:

本文探讨了一种以 Minkowski 核心和亚普朗克曲率为特征的正则黑洞(BH)的准正规模态(QNMs)性质。在关注一个特殊情形时,该正则黑洞表现出与 Hayward 黑洞以及某些圈量子引力修正(LQG-corrected)黑洞相同的大尺度行为。与 Schwarzschild 黑洞(SS-BH)相比,该正则黑洞中 QNMs 的一个显著特征是泛音的明显爆发。这种爆发可归因于量子引力效应导致的近视界几何区域相对于 SS-BH 的偏离。此外,我们将该正则黑洞的 QNM 性质与 Hayward 黑洞和 LQG 修正黑洞的 QNM 性质进行了比较。在泛音模态中也观察到类似的泛音爆发现象。总之,QNMs 可能成为探测量子引力效应并区分不同黑洞模型的有力工具。

英文摘要:

This paper explores the properties of the quasinormal modes (QNMs) of a regular black hole(BH) characterized by a Minkowski core and sub-Planckian curvature. When focusing on a special case, this regular BH exhibits identical large-scale behavior with the Hayward BH and some loop quantum gravity corrected (LQG-corrected) BH. A notable characteristic of the QNMs in this regular BH is the pronounced outburst of overtones when compared to the Schwarzschild BH (SS-BH). This outburst can be attributed to the deviation from the SS-BH in the near-horizon geometry region due to the quantum gravity effect. Furthermore, we compare the QNM properties of the regular BH with those of the Hayward BH and the LQG-corrected BH. A similar phenomenon of overtone outburst is observed in the modes of the overtone. As a conclusion, the QNMs may be a powerful tool for detecting the quantum gravity effect and distinguishing different BH models.
