论文摘要
考虑到CFT冲击波对Jackiw-Teitelboim重力中永恒黑洞的纠缠结构的影响，该重力在热平衡中使用热浴。冲击波将能量和熵带入黑洞，并加热黑洞，从而导致蒸发和最终恢复平衡。我们找到了半经典高温方案中整个松弛过程的分析描述。如果在页面时间周围插入冲击波，则可能会根据参数几个方案。页面时间可以延迟或加速，并且可以有多个过渡。最终的熵马鞍具有一个量子极端表面，该表面通常从地平线内部开始，但在以后的某个时间移动。通常，增加的冲击波能量和缓慢的蒸发速率有利于极端表面在地平线内。冲击波还破坏了黑洞的争夺性能。然后将相同的分析应用于插入具有相似结论的极端黑洞中的冲击波。
The effect of a CFT shockwave on the entanglement structure of an eternal black hole in Jackiw-Teitelboim gravity, that is in thermal equilibrium with a thermal bath, is considered. The shockwave carries energy and entropy into the black hole and heats the black hole up leading to evaporation and the eventual recovery of equilibrium. We find an analytical description of the entire relaxational process within the semiclassical high temperature regime. If the shockwave is inserted around the Page time then several scenarios are possible depending on the parameters. The Page time can be delayed or hastened and there can be more than one transition. The final entropy saddle has a quantum extremal surface that generically starts inside the horizon but at some later time moves outside. In general, increased shockwave energy and slow evaporation rate favour the extremal surface to be inside the horizon. The shockwave also disrupts the scrambling properties of the black hole. The same analysis is then applied to a shockwave inserted into the extremal black hole with similar conclusions.
