多重冲击

Multiple Shocks

Stephen H. Shenker, Douglas Stanford

摘要:

利用规范/引力对偶,我们研究了一类具有很大纠缠度,但局域双边关联很弱的两个CFTs的态。这些状态是通过扰动的热场双态与热标度运营商,在不同的时间是本地的。作用于双黑洞几何结构,这些扰动产生了一个交叉的冲击波网络,支持一个非常长的虫洞。混沌CFT动力学和相关的快速加扰时间在确定所产生的几何形状的定性特征中起着至关重要的作用。

英文摘要:

Using gauge/gravity duality, we explore a class of states of two CFTs with a large degree of entanglement, but with very weak local two-sided correlation. These states are constructed by perturbing the thermofield double state with thermal-scale operators that are local at different times. Acting on the dual black hole geometry, these perturbations create an intersecting network of shock waves, supporting a very long wormhole. Chaotic CFT dynamics and the associated fast scrambling time play an essential role in determining the qualitative features of the resulting geometries.
