平板全息中的纠缠负性

Entanglement Negativity in Flat Holography

Debarshi Basu, Ashish Chandra, Himanshu Parihar, Gautam Sengupta

摘要:

本文提出了一类与Einstein引力和拓扑质量引力描述的渐近平坦三维体几何对偶的$(1+1)-$维伽利略共形场论中两体态纠缠负性的全息构造.建筑涉及特定的代数总和的长度同源的散装极值曲线的某些组合的间隔适当的这种二分状态。我们的分析准确地再现了相应的复制技术的结果在大的中心荷限制。我们证实了我们的建设,通过半经典的分析,涉及的情况下,两个不相交的间隔在这样的伽利略共形场论双散装爱因斯坦引力的几何monodromy技术。

英文摘要:

We advance holographic constructions for the entanglement negativity of bipartite states in a class of $(1+1)-$dimensional Galilean conformal field theories dual to asymptotically flat three dimensional bulk geometries described by Einstein Gravity and Topologically Massive Gravity. The construction involves specific algebraic sums of the lengths of bulk extremal curves homologous to certain combinations of the intervals appropriate to such bipartite states. Our analysis exactly reproduces the corresponding replica technique results in the large central charge limit. We substantiate our construction through a semi classical analysis involving the geometric monodromy technique for the case of two disjoint intervals in such Galilean conformal field theories dual to bulk Einstein Gravity.
