黑洞的线性扰动:稳定性、准正规模和尾

Linear perturbations of black holes: stability, quasi-normal modes and tails

Alexander Zhidenko

摘要:

黑洞有其固有的振荡,称为准正规模。天体物理学黑洞的固有振荡在不久的将来可以借助引力波探测器观测到。准正规模在测试黑色物体的稳定性、反德西特/共形场论(AdS/CFT)对应以及更高维度理论(例如膜世界场景和弦论)中也非常重要。本论文回顾了大量的工作,这些工作提供了一个广泛的类黑洞在四维和更高维的各种自旋和引力微扰的领域的准正规谱的深入研究。我们用数值方法研究了准正规模对一些因素的依赖性,如时空中存在宇宙学常数、Gauss-Bonnet参数或以太,以及谱对黑洞和场参数的依赖性。通过对拟正规谱的分析,我们研究了高维Reissner-Nordstrom-deSitter黑洞,具有压缩视界的Kaluza-Klein黑洞,Gauss-Bonnet黑洞和黑弦的稳定性.特别注意各种黑洞背景下质量场的演化。我们考虑了它们的准正态振铃和晚时尾。此外,我们提出了两个新的数值技术:一个概括的Nollert改进的Frobenius方法高维问题和一个定性的新方法,它允许计算准正常频率的黑洞,其中的度量是不知道的分析。

英文摘要:

Black holes have their proper oscillations, which are called the quasi-normal modes. The proper oscillations of astrophysical black holes can be observed in the nearest future with the help of gravitational wave detectors. Quasi-normal modes are also very important in the context of testing of the stability of black objects, the anti-de Sitter/Conformal Field Theory (AdS/CFT) correspondence and in higher dimensional theories, such as the brane-world scenarios and string theory. This dissertation reviews a number of works, which provide a thorough study of the quasi-normal spectrum of a wide class of black holes in four and higher dimensions for fields of various spin and gravitational perturbations. We have studied numerically the dependance of the quasi-normal modes on a number of factors, such as the presence of the cosmological constant, the Gauss-Bonnet parameter or the aether in the space-time, the dependance of the spectrum on parameters of the black hole and fields under consideration. By the analysis of the quasi-normal spectrum, we have studied the stability of higher dimensional Reissner-Nordstrom-de Sitter black holes, Kaluza-Klein black holes with squashed horizons, Gauss-Bonnet black holes and black strings. Special attention is paid to the evolution of massive fields in the background of various black holes. We have considered their quasi-normal ringing and the late-time tails. In addition, we present two new numerical techniques: a generalisation of the Nollert improvement of the Frobenius method for higher dimensional problems and a qualitatively new method, which allows to calculate quasi-normal frequencies for black holes, which metrics are not known analytically.
