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 ...
The Ryu-Takayanagi formula provides the entanglement entropy of quantum field theory as an area of the minimal surface (Ryu-Takayangi surface) in a corresp... J Tsujimura,Y Nambu - 《Arxiv》 被引量: 0发表: 2020年 Null wave front as Ryu-Takayanagi surface The Ryu-Takayanagi formula provides...
Furthermore, in appropriate semiclassical limits our entropies are computed by the RT-formula with quantum corrections. 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 ...
