CFT $_2$基态的截止依赖性和复杂性

Cutoff Dependence and Complexity of the CFT$_2$ Ground State

Bowen Chen, Bartlomiej Czech, Zi-zhi Wang

摘要:

本文将二维共形场论(CFT $_2$)的真空描述为$SL(2,\mathbb{R}) \times SL(2,\mathbb{R})$ Chern-Simons理论中Wilson线的网络,该理论通常用于研究三维反德西特空间(AdS $_3$)中的引力.网络的位置和形状编码了定义基态密度算符的截止尺度。一个一般的论点建议确定“密度的复杂性”的网络与外在曲率的截止面在AdS $_3$,这是由高斯-邦纳定理同意全息复杂性=体积的建议。

英文摘要:

We present the vacuum of a two-dimensional conformal field theory (CFT$_2$) as a network of Wilson lines in $SL(2,\mathbb{R}) \times SL(2,\mathbb{R})$ Chern-Simons theory, which is conventionally used to study gravity in three-dimensional anti-de Sitter space (AdS$_3$). The position and shape of the network encode the cutoff scale at which the ground state density operator is defined. A general argument suggests identifying the `density of complexity' of this network with the extrinsic curvature of the cutoff surface in AdS$_3$, which by the Gauss-Bonnet theorem agrees with the holographic Complexity = Volume proposal.
