利用AdS/CFT猜想提取时空:II部分

Extracting Spacetimes using the AdS/CFT Conjecture: Part II

Samuel Bilson

摘要:

受全息原理的启发,在AdS/CFT对应的背景下,在大的t 'Hooft极限,我们研究如何在给定的物理量的双重边界CFT的信息,某些高度对称的体时空的几何可以恢复。特别地,我们使用全息纠缠熵的建议(涉及的纠缠熵的某些子系统的边界上的静态极小曲面的面积)恢复体度规使用高维极小曲面探测一类静态,平面对称,渐近AdS时空。我们分别找到了边界理论中直带子系统和圆盘子系统的纠缠熵度量函数的解析表达式和微扰表达式。最后,我们讨论如何提取可以推广。

英文摘要:

Motivated by the holographic principle, within the context of the AdS/CFT Correspondence in the large t'Hooft limit, we investigate how the geometry of certain highly symmetric bulk spacetimes can be recovered given information of physical quantities in the dual boundary CFT. In particular, we use holographic entanglement entropy proposal (relating the entanglement entropy of certain subsystems on the boundary to the area of static minimal surfaces) to recover the bulk metric using higher dimensional minimal surface probes within a class of static, planar symmetric, asymptotically AdS spacetimes. We find analytic and perturbative expressions for the metric function in terms of the entanglement entropy of straight belt and circular disk subsystems of the boundary theory respectively. Finally, we discuss how such extractions can be generalised.
