论文摘要
最近，据报道，施瓦茨柴尔德黑洞背景中大量标量场的准标准场的准模式的异常衰减速率，其中最长的寿命模式是具有较高角度数的模式，对于临界值小于临界值的标量场质量较高，而超出该值以外的行为的临界值是倒置的。在这项工作中，我们将研究扩展到其他渐近几何形状，例如Schwarzschild-de保姆和Schwarzschild-Ads黑洞。主要是，我们发现这种行为和临界质量存在于Schwarzschild-de保姆背景中。同样，我们发现，当宇宙常数增加以及夸顿数量增加时，临界质量的值会增加。另一方面，尽管施瓦茨柴尔兹山（Schwarzschild-Ads）黑洞背景中不存在临界质量，但准模式的衰减速率始终表现出异常的行为。
Recently an anomalous decay rate of the quasinormal modes of a massive scalar field in Schwarzschild black holes backgrounds was reported in which the longest-lived modes are the ones with higher angular number, for a scalar field mass smaller than a critical value, while that beyond this value the behaviour is inverted. In this work, we extend the study to other asymptotic geometries, such as, Schwarzschild-de Sitter and Schwarzschild-AdS black holes. Mainly, we found that such behaviour and the critical mass are present in the Schwarzschild-de Sitter background. Also, we found that the value of the critical mass increases when the cosmological constant increases and also when the overtone number is increasing. On the other hand, despite the critical mass is not present in Schwarzschild-AdS black holes backgrounds, the decay rate of the quasinormal modes always exhibits an anomalous behaviour.
