复杂性和Shock Wave几何

Complexity and Shock Wave Geometries

Douglas Stanford, Leonard Susskind

摘要:

本文改进了一个关于爱因斯坦-罗森桥的尺寸与对偶量子态的计算复杂度之间的关系的猜想。我们的改进指出,复杂性是成比例的ERB的空间体积。更准确地说,直到一个模糊的数值系数,我们提出的复杂性是正则化的体积的最大余维一个表面通过桥梁,除以$G_N l_{AdS}$。我们测试这个猜想对各种各样的球对称冲击波几何形状在不同的维度。我们找到了详细的协议。

英文摘要:

In this paper we refine a conjecture relating the time-dependent size of an Einstein-Rosen bridge to the computational complexity of the of the dual quantum state. Our refinement states that the complexity is proportional to the spatial volume of the ERB. More precisely, up to an ambiguous numerical coefficient, we propose that the complexity is the regularized volume of the largest codimension one surface crossing the bridge, divided by $G_N l_{AdS}$. We test this conjecture against a wide variety of spherically symmetric shock wave geometries in different dimensions. We find detailed agreement.
