论文摘要
我们研究了热菲尔德双状态双重双重扰动到带电广告的黑洞。我们通过散装中的无质量带外壳对扰动进行建模。与中性情况不同，所有此类壳体都以明确的半径弹跳，可以在地平线后面。我们表明，争夺时间的标准“冲击波”计算表明，增加电荷会增加争夺时间。然后，我们使用反弹提出了两个参数，即在添加充电时，扰乱实际上并不需要更长的时间，而是延迟了它的开始。我们还构建了一个边界四点函数，该功能检测出壳是否在黑洞内弹跳。
We study charged perturbations of the thermofield double state dual to a charged AdS black hole. We model the perturbation by a massless charged shell in the bulk. Unlike the neutral case, all such shells bounce at a definite radius, which can be behind the horizon. We show that the standard "shock wave" calculation of a scrambling time indicates that adding charge increases the scrambling time. We then give two arguments using the bounce that suggest that scrambling does not actually take longer when charge is added, but instead its onset is delayed. We also construct a boundary four point function which detects whether the shell bounces inside the black hole.
