旋转BTZ黑洞局部扰动的置乱时间

Scrambling time from local perturbations of the rotating BTZ black hole

Andrius Štikonas

摘要:

本文研究了旋转BTZ黑洞受大质量反作用自由落体粒子扰动时的纠缠熵。然后,在两个旋转BTZ的渐近区域的两个有限区间之间的互信息。它允许我们找到加扰时间,即互信息消失的时间尺度。我们给出了一个双大$c$ CFT描述的温度场双态的左,右移动模式,是由一个本地运营商扰动。重力和CFT结果之间的精确匹配。

英文摘要:

In this paper, we investigate the entanglement entropy of the rotating BTZ black hole perturbed by a massive back-reacting free falling particle. Then, mutual information between two finite intervals in two asymptotic regions of rotating BTZ is derived. It allows us to find the scrambling time, the time scale in which mutual information vanishes. We give a dual large $c$ CFT description in terms of a thermofield double state with different temperatures for left and right moving modes that is perturbed by a local operator. Exact matching between gravity and CFT results is obtained.
