AdS/CFT中的ISCO

ISCOs in AdS/CFT

David Berenstein, Ziyi Li, Joan Simon

摘要:

研究了不同维球对称AdS黑洞中的稳定圆轨道及其极限最内层稳定圆轨道(ISCO)。在大质量黑洞中,我们给出了它们的大小、角速度和角动量的解析表达式。双重解释是在亚稳态不热化在典型的热尺度,其存在是由于非微扰效应的空间曲率。我们的计算再现了文献中已知的结合能,但也包括了对应于近圆形轨迹的径向波动中的结合能。我们还描述了粒子如何放置在这些轨道上的边界上的集成运营商:他们隧道内的方式,可以计算从复杂的测地线在黑洞背景和从WKB近似的波动方程。我们解释这两个计算是如何相关的。

英文摘要:

We study stable circular orbits in spherically symmetric AdS black holes in various dimensions and their limiting innermost stable circular orbits (ISCOs). We provide analytic expressions for their size, angular velocity and angular momentum in a large black hole mass regime. The dual interpretation is in terms of meta-stable states not thermalising in typical thermal scales and whose existence is due to non-perturbative effects on the spatial curvature. Our calculations reproduce the binding energy known in the literature, but also include a binding energy in the radial fluctuations corresponding to near circular trajectories. We also describe how particles are placed on these orbits from integrated operators on the boundary: they tunnel inside in a way that can be computed from both complex geodesics in the black hole background and from the WKB approximation of the wave equation. We explain how these two computations are related.
