论文摘要
在这项工作中,我们考虑了一个广义的布朗尼科夫 - 艾利斯虫洞和无独特的莫里斯·托恩虫洞,我们研究了大规模标量场的传播。我们使用WKB方法和伪chebyshev方法计算了准频率,我们在广义Bronnikov-ellis虫洞中显示了准模式中存在异常衰减率。但是,对于莫里斯 - thorne虫洞背景中的基本模式,避免了这种异常行为。
In this work we consider a Generalized Bronnikov-Ellis wormhole and the tideless Morris-Thorne wormhole and we study the propagation of massive scalar fields. We calculate the quasinormal frequencies using the WKB method and the pseudospectal Chebyshev method and we show the presence of an anomalous decay rate for the quasinormal modes in the Generalized Bronnikov-Ellis wormhole. However, such anomalous behaviour is avoided for the fundamental mode in the Morris-Thorne wormhole background.
