量子极值曲面:超越经典体系的全息纠缠熵

Quantum Extremal Surfaces: Holographic Entanglement Entropy beyond the Classical Regime

Netta Engelhardt, Aron C. Wall

摘要:

我们提出全息纠缠熵可以计算在任意数量级的体普朗克常量使用的“量子极值表面”的概念:一个表面,极值的广义熵,即面积和体积纠缠熵的总和。在体量子校正的首阶,我们的建议同意福克纳,Lewkowycz,和Maldacena的公式,这是只在这个顺序导出;超出首阶校正,两个示意图分歧。量子极值曲面位于边界区域及其补充区域的因果影响域之外,并且在某些时空中存在阻止它们进入某些区域的障碍。我们评论散装重建的影响。

英文摘要:

We propose that holographic entanglement entropy can be calculated at arbitrary orders in the bulk Planck constant using the concept of a "quantum extremal surface": a surface which extremizes the generalized entropy, i.e. the sum of area and bulk entanglement entropy. At leading order in bulk quantum corrections, our proposal agrees with the formula of Faulkner, Lewkowycz, and Maldacena, which was derived only at this order; beyond leading order corrections, the two conjectures diverge. Quantum extremal surfaces lie outside the causal domain of influence of the boundary region as well as its complement, and in some spacetimes there are barriers preventing them from entering certain regions. We comment on the implications for bulk reconstruction.
