论文摘要
我们以数值计算Klein-Gordon和Dirac场的准频率在二维尺寸降低的BTZ黑洞中进行计算。我们的工作扩展了以前发表的有关该黑洞阻尼振荡的结果。首先，我们计算最小耦合的klein-gordon场的准频率，用于一系列尺寸降低的BTZ黑洞物理参数，而先前尚未分析。此外，我们首次确定狄拉克场的准频率在尺寸降低的BTZ黑洞中传播。对于Dirac字段，我们使用Horowitz-Hubeny方法和渐近迭代方法，而对于Klein-Gordon场，先前结果的扩展基于渐近迭代方法。最后，我们讨论了我们的主要结果。
We calculate numerically the quasinormal frequencies of the Klein-Gordon and Dirac fields moving in the two-dimensional dimensionally reduced BTZ black hole. Our work extends results previously published on the damped oscillations of this black hole. First, we compute the quasinormal frequencies of the minimally coupled Klein-Gordon field for a range of the dimensionally reduced BTZ black hole physical parameters that is not previously analyzed. Furthermore we determine, for the first time, the quasinormal frequencies of the Dirac field propagating in the dimensionally reduced BTZ black hole. For the Dirac field we use the Horowitz-Hubeny method and the asymptotic iteration method, while for the Klein-Gordon field the extension of the previous results is based on the asymptotic iteration method. Finally we discuss our main results.
