论文摘要
我们提出了极端表面的缺陷，作为边界量子极端表面的全息表面。缺陷表面是通过最大程度地减少通过缺陷理论校正的Ryu-Takayanagi表面来定义的。当RT表面在缺陷上交叉或终止时，这一点尤其有趣。在简单的AD/BCFT设置中，我们发现缺陷极端表面公式与边界量子极端表面的结果完全相同。我们提供了一个具有缺陷brane的广告大量的分解程序，以清楚地看到岛公式是如何从重力粘贴到平坦空间量子场理论的Brane World系统中出现的。
We propose defect extremal surface as the holographic counterpart of boundary quantum extremal surface. The defect extremal surface is defined by minimizing the Ryu-Takayanagi surface corrected by the defect theory. This is particularly interesting when the RT surface crosses or terminates on the defect. In a simple set up of AdS/BCFT, we find that the defect extremal surface formula gives precisely the same results of the boundary quantum extremal surface. We provide a decomposition procedure of an AdS bulk with a defect brane to see clearly how Island formula emerges from a brane world system with gravity glued to a flat space quantum field theory.
