论文摘要

我们研究了一个常规的黑洞时空的无质量标量场扰动,包括准模式光谱和环down波形,该时期是通过环量子重力量子量化的,该量子的量子量子灵感$ 4 $ d黑洞。与文献中考虑的其他常规黑洞中的大多数(如果不是全部)相反,所得的非发挥时空具有单个分叉的范围,因此没有大规模通胀。在内部,面积半径降低到由聚合常数($ k $)给出的最小值,然后重新扩展为Kantowski-Sachs宇宙。我们发现,这种黑洞模型在小标量扰动上是稳定的。我们还表明,$ k $的幅度增加将降低QNM电位的高度,并以较低的频率和较小的阻尼产生振荡。

We investigate the massless scalar field perturbations, including the quasinormal mode spectrum and the ringdown waveform, of a regular black hole spacetime that was derived via the Loop Quantum Gravity inspired polymer quantization of spherical $4$D black holes. In contrast to most, if not all, of the other regular black holes considered in the literature, the resulting nonsingular spacetime has a single bifurcative horizon and hence no mass inflation. In the interior, the areal radius decreases to a minimum given by the Polymerization constant, $k$, and then re-expands into a Kantowski-Sachs universe. We find indications that this black hole model is stable against small scalar perturbations. We also show that an increase in the magnitude of $k$ will decrease the height of the QNM potential and gives oscillations with lower frequency and less damping.
