论文摘要
我们研究了以两个环路量子重力（LQG）校正参数为特征的常规环量子黑洞（LQBH）的背景几何形状上的测试标量场的演变，即聚合物功能和最小面积间隙。在高阶WKB膨胀和相关的PADé近似值，改进的渐近迭代方法（AIM）和时间域积分的帮助下，进行了渐近平坦时空中的准频率的计算。研究了该理论的自由参数对准模式的影响，并研究了与Schwarzschild BHS的偏差。我们表明，LQG校正参数对准频率具有相反的影响，而LQBHS动态稳定。
We study the evolution of a test scalar field on the background geometry of a regular loop quantum black hole (LQBH) characterized by two loop quantum gravity (LQG) correction parameters, namely, the polymeric function and the minimum area gap. The calculations of quasinormal frequencies in asymptotically flat spacetime are performed with the help of higher-order WKB expansion and related Padé approximants, the improved asymptotic iteration method (AIM), and time-domain integration. The effects of free parameters of the theory on the quasinormal modes are studied and deviations from those of the Schwarzschild BHs are investigated. We show that the LQG correction parameters have opposite effects on the quasinormal frequencies and the LQBHs are dynamically stable.
