提出了一种在渐近AdS时空中恢复体信息的迭代方法。我们考虑零能类空测地线和它们与三维纠缠熵的关系,以确定在某些对称情况下的度量。与arXiv:hep-th/0609202中提出的替代提取方法进行了一些比较,然后将这两种方法结合起来,以允许在最一般类型的静态球对称设置中进行度量恢复。最后,我们提取的质量和密度分布的玩具模型的例子中的气体的辐射(2 + 1)维AdS。
An iterative method for recovering the bulk information in asymptotically AdS spacetimes is presented. We consider zero energy spacelike geodesics and their relation to the entanglement entropy in three dimensions to determine the metric in certain symmetric cases. A number of comparisons are made with an alternative extraction method presented in arXiv:hep-th/0609202, and the two methods are then combined to allow metric recovery in the most general type of static, spherically symmetric setups. We conclude by extracting the mass and density profiles for a toy model example of a gas of radiation in (2 + 1)-dimensional AdS.
