摘要

我们研究了五维迈尔斯-佩里黑洞背景下大质量标量场的准正态模式。特别地，我们探讨了具有两个任意旋转参数的迈尔斯-佩里黑洞的情况。由于标量场的Klein-Gordon方程是可分的，我们用径向方程和角方程数值计算标量拟正态模态。数值计算采用了连分式法和矩阵法两种方法。我们发现所有得到的模态都有负虚部并且是衰减模态。我们还考虑了旋转参数、标量场质量μ和方位角数对标量拟正态模态的影响。此外，当标量质量μ变大时，我们还发现了长寿命的标量模态。我们的数值结果也明确地证明了QNMs的对称性。

Quasinormal modes of massive scalar fields in five-dimensional Myers-Perry black holes with two arbitrary rotation parameters

We investigate the quasinormal modes of massive scalar fields in the background of five-dimensional Myers-Perry black holes. In particular, we explore the case for Myers-Perry black holes with two arbitrary rotation parameters. Since the Klein-Gordon equation for the scalar field is separable, we numerically compute the scalar quasinormal modes by using the radial and angular equations. Two methods, the continued fraction method and matrix method, are used in the numerical calculation. We find that all obtained modes have negative imaginary parts and are decaying modes. We also consider the impact of the rotation parameters, scalar field mass μ and azimuthal numbers on the scalar quasinormal modes. Besides, when the scalar mass μ becomes relatively large, we also find the long-living scalar modes. Our numerical results also demonstrate the symmetries of the QNMs explicitly.
