标题： Higher-spin localized shocks

摘要： 在AdS/CFT的背景下，引力冲击波是边界量子混沌的几何表现。 我们研究了涉及任意数量的玻色场的一般微分同胚不变理论中的这一联系。 具体而言，我们证明包含自旋-2或更高自旋场的理论通常在黑洞背景上允许经典的局域冲击波解，而自旋-0和自旋-1理论则不允许。 与引力情况类似，这些高自旋冲击波提供了一种计算时间有序以外关联函数的方法。 发现李雅普诺夫指数和蝴蝶速度普遍与极点跳过的预测一致。 特别是，高自旋场会导致违反混沌界限的李雅普诺夫指数以及可能超过光速的蝴蝶速度。 显示英文摘要

摘要： In the context of AdS/CFT, gravitational shockwaves serve as a geometric manifestation of boundary quantum chaos. We study this connection in general diffeomorphism-invariant theories involving an arbitrary number of bosonic fields. Specifically, we demonstrate that theories containing spin-2 or higher-spin fields generally admit classical localized shockwave solutions on black hole backgrounds, whereas spin-0 and spin-1 theories do not. As in the gravitational case, these higher-spin shockwaves provide a means to compute the out-of-time-order correlator. Both the Lyapunov exponent and the butterfly velocity are found to universally agree with predictions from pole skipping. In particular, higher-spin fields lead to a Lyapunov exponent that violates the chaos bound and a butterfly velocity that may exceed the speed of light.
