Abstract

Two models for Schwarzschild-like black holes with quantum corrections, derived from the Hamiltonian constraints approach to quantum gravity while preserving general covariance, have been developed in Zhang et al. (Phys. Rev. D 111, L081504, 2025, arXiv:2407.10168 [gr-qc]). In this work, we study the quasinormal modes of a massive scalar field and demonstrate that the spectrum includes arbitrarily long-lived modes, known as quasi-resonances. Precise calculations using the Leaver method show good agreement with WKB data and time-domain integration within the range where these methods are reliable, specifically for small field masses.

有效量子引力中的长寿命准正态模

Zhang等人已经开发了两个具有量子修正的类史瓦西黑洞模型，这些模型来自量子引力的哈密顿约束方法，同时保留了一般协方差。[j] .中国机械工程，2016,26(1):1 - 4。在这项工作中，我们研究了一个大质量标量场的准正态模式，并证明了谱包括任意长寿命模式，称为准共振。使用Leaver方法进行的精确计算表明，在这些方法可靠的范围内，特别是对于小场质量，与WKB数据和时域积分具有良好的一致性。
