标题： Bouncing inside the horizon and scrambling delays

摘要： 我们研究与带电AdS黑洞对偶的热场双态的带电扰动。 我们通过体中的无质量带电壳层来模拟这种扰动。 与中性情况不同，所有这样的壳层都会在确定的半径处反弹，这可能位于视界之后。 我们表明，标准的“冲击波”计算表明，增加电荷会增加混淆时间。 然后我们利用反弹给出两个论点，表明当添加电荷时，混淆实际上并没有花费更长时间，而是其开始被延迟了。 我们还构建了一个边界四点函数，用于检测壳层是否在黑洞内部反弹。 显示英文摘要

摘要： 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.
