动量/复杂性对应的证明

Proof of a Momentum/Complexity Correspondence

J. L. F. Barbon, J. Martin-Garcia, M. Sasieta

摘要:

我们表明,全息复杂性=体积的建议满足一个非常普遍的概念的动量/复杂性对应(PC),基于广义相对论的动量约束。它将复杂性变化率与通过类空极值曲面的适当物质动量通量联系起来。这使物质的“引力聚集”增加了复杂性的直观想法形式化,所需的“下落动量”概念被证明有一个表达这一想法的牛顿化身。PC对应的建议形式被发现是精确的爱因斯坦方程的任何解决方案在2+1维,任何球对称的解决方案在任意尺寸,推广所有以前的计算使用球形薄壳。引力辐射通过修正进入,修正不能直接解释为PC对应。其他阻碍精确的PC对偶性的障碍有一个拓扑起源,并在虫洞的存在下出现。

英文摘要:

We show that the holographic Complexity = Volume proposal satisfies a very general notion of Momentum/Complexity correspondence (PC), based on the Momentum Constraint of General Relativity. It relates the rate of complexity variation with an appropriate matter momentum flux through spacelike extremal surfaces. This formalizes the intuitive idea that `gravitational clumpling' of matter increases complexity, and the required notion of `infall momentum' is shown to have a Newtonian avatar which expresses this idea. The proposed form of the PC correspondence is found to be exact for any solution of Einstein's equations in 2+1 dimensions, and any spherically symmetric solution in arbitrary dimensions, generalizing all previous calculations using spherical thin shells. Gravitational radiation enters through a correction which does not have a straightforward interpretation as a PC correspondence. Other obstructions to an exact PC duality have a topological origin and arise in the presence of wormholes.
