标题： Quasinormal frequencies of the dimensionally reduced BTZ black hole

摘要： 我们数值计算了在二维降维BTZ黑洞中运动的Klein-Gordon场和Dirac场的准正则频率。我们的工作扩展了之前发表的关于该黑洞阻尼振荡的结果。首先，我们计算了在之前未分析的二维降维BTZ黑洞物理参数范围内，最小耦合的Klein-Gordon场的准正则频率。此外，我们首次确定了在二维降维BTZ黑洞中传播的Dirac场的准正则频率。对于Dirac场，我们使用了Horowitz-Hubeny方法和渐近迭代方法，而对于Klein-Gordon场，之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。 显示英文摘要

摘要： 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.
