论文摘要
反射的熵是量子信息中新提出的概念。它在全息图中具有重要意义。在这项工作中，我们研究了广告$ _3 $/wcft信函框架中的反射熵。我们通过概括均匀化图并考虑了电荷保护，确定了非亚伯Orbifold WCFT中各种扭曲操作员的缩放维度和电荷。这使我们能够计算反射的熵，对数负性和奇怪的熵，以在全息wcft中进行两个不相交的间隔。我们发现反射的熵可以与截面前楔形截面有关，这是由两个摆动表面的长凳之间的最小距离给出的。
Reflected entropy is a newly proposed notion in quantum information. It has important implications in holography. In this work, we study the reflected entropy in the framework of the AdS$_3$/WCFT correspondence. We determine the scaling dimensions and charges of various twist operators in non-Abelian orbifold WCFT by generalizing the uniformization map and taking into account of the charge conservation. This allows us to compute the reflected entropy, logarithmic negativity and odd entropy for two disjoint intervals in holographic WCFT. We find that the reflected entropy can be related holographically to the pre-entanglement wedge cross-section, which is given by the minimal distance between the benches in two swing surfaces.
