我们研究黑洞内部的局部冲击波之间的碰撞。我们给出了一个全息边界描述的共享量子电路中的两个增长的微扰的重叠的过程。扰动既以指数方式增长,也以弹道方式增长。由于不同的物理效应之间的竞争,电路分析表明依赖于横向位置,并表现出四个制度的性质不同的行为。在重力方面,我们研究碰撞后的几何形状的属性,在简单的设置和估计,在更一般的情况下,使用精确的计算。我们表明,电路分析提供了直观的和令人惊讶的准确预测引力计算涉及广义相对论的非线性特征。
We study collisions between localized shockwaves inside a black hole interior. We give a holographic boundary description of this process in terms of the overlap of two growing perturbations in a shared quantum circuit. The perturbations grow both exponentially as well as ballistically. Due to a competition between different physical effects, the circuit analysis shows dependence on the transverse locations and exhibits four regimes of qualitatively different behaviors. On the gravity side we study properties of the post-collision geometry, using exact calculations in simple setups and estimations in more general circumstances. We show that the circuit analysis offers intuitive and surprisingly accurate predictions about gravity computations involving non-linear features of general relativity.
