黑洞的准正规模:从天体物理学到弦论

Quasinormal modes of black holes: from astrophysics to string theory

R. A. Konoplya, A. Zhidenko

摘要:

黑洞的微扰最初是在可能观测到的天体物理效应的背景下被考虑的,在过去的十年里,它已经在弦论、膜世界模型和量子引力中被研究。通过著名的规范/引力对偶性,扰动黑洞的固有振荡,称为准正规模(quasinormal modes,QNM),允许在强耦合的对偶有限温度场论中描述流体动力学区域,它可以用来预测非微扰区域中夸克-胶子等离子体的行为.另一方面,膜世界假设在自然界中存在额外维度,因此多维黑洞可以在实验室实验中形成。这些都激发了近年来对高维黑洞和膜的微扰的研究。在这篇综述中,讨论了黑洞扰动的各个方面的最新成就,如变量的解耦的扰动方程,准正规模式(特别强调各种数值和分析计算方法),晚时间尾巴,引力稳定性,AdS/CFT解释的准正规模式,全息超导体。我们还触及国家的最先进的观测可能性检测准正规模式的黑洞。

英文摘要:

Perturbations of black holes, initially considered in the context of possible observations of astrophysical effects, have been studied for the past ten years in string theory, brane-world models and quantum gravity. Through the famous gauge/gravity duality, proper oscillations of perturbed black holes, called quasinormal modes (QNMs), allow for the description of the hydrodynamic regime in the dual finite temperature field theory at strong coupling, which can be used to predict the behavior of quark-gluon plasmas in the nonperturbative regime. On the other hand, the brane-world scenarios assume the existence of extra dimensions in nature, so that multidimensional black holes can be formed in a laboratory experiment. All this stimulated active research in the field of perturbations of higher-dimensional black holes and branes during recent years. In this review recent achievements on various aspects of black hole perturbations are discussed such as decoupling of variables in the perturbation equations, quasinormal modes (with special emphasis on various numerical and analytical methods of calculations), late-time tails, gravitational stability, AdS/CFT interpretation of quasinormal modes, and holographic superconductors. We also touch on state-of-the-art observational possibilities for detecting quasinormal modes of black holes.
