Ryu-Takayanagi公式及其应用的科普。对我来说不是很好玩。毕竟,全息对偶说引力=场论,黑洞热力学说面积=熵,结合就有了面积=纠缠,这几个口号已经把思想框架概括完了,可是它们本质上都还是半经典的结果,怎么也给不出量子引力的。相比起来我更喜欢经典主题:黑洞的膜构造,模糊球。链接 发布于 2021-11-29 00:58 ...
我们提出了一种确定性的算法,用于确定AdS 3 / CFT 2中的Ryu-Takayanagi表面,该算法利用了之前提到的全息纠缠熵和最大流量/最小切割之间的联系。 然后,我们将其复杂性描述为多项式时间算法。点赞(0) 踩踩(0) 反馈 所需:1 积分 电信网络下载 数据结构与算法 全 数据结构与算法全 ```Java ...
Ryu-TakayanagiformulasymmetricWe consider the special case of random tensor networks (RTNs) endowed with gauge symmetry constraints on each tensor. We compute the R茅nyi entropy for such states and recover the Ryu-Takayanagi (RT) formula in the large-bond regime. The result provides first of ...
I argue that an analogy between emergent gauge theories and the bulk in AdS/CFT suggests that the Ryu-Takayanagi area term is a boundary entropy, counting the number of ways UV degrees of freedom in the bulk can satisfy an emergent gauge constraint for gravity at the entangling surface. Throu...

Our work thus provides a Hilbert space interpretation of the Ryu-Takayanagi entropy. Since our axioms do not severely constrain UV bulk structures, it is plausible that they hold equally well for successful formulations of string field theory, spin-foam models, or any other approach to ...
