论文摘要
边界保形场理论（BCFT）和界面形式结构场理论（ICFT）在信息悖论问题的背景下吸引了人们的注意。在这种背景下，我们发展了BCFT/ICFT中反射熵的想法。我们首先在BCFT中引入了左右反射的熵（LRRE），并表明其全息双重双重由ADS/BCFT纠缠楔形截面（EWC）的面积给出。我们还提出了如何评估ICFT中反射的熵。通过使用此技术，我们可以在某些特殊情况下显示马尔可夫差距的普遍行为。此外，我们通过使用此LRRE/EWCS双重性来阐明边界主要相关函数的全息二。
Boundary conformal field theory (BCFT) and interface conformal field theory (ICFT) attract attention in the context of the information paradox problem. On this background, we develop the idea of the reflected entropy in BCFT/ICFT. We first introduce the left-right reflected entropy (LRRE) in BCFT and show that its holographic dual is given by the area of the entanglement wedge cross section (EWCS) through AdS/BCFT. We also present how to evaluate the reflected entropy in ICFT. By using this technique, we can show the universal behavior of the Markov gap in some special cases. Furthermore, we clarify what is the holographic dual of boundary primary correlation functions by using this LRRE/EWCS duality.
