Abstract
We propose defect extremal surface as the holographic counterpart of boundary quantum extremal surface. The prescription minimizes a Ryu–Takayanagi surface corrected by the quantum theory localized on the defect and reproduces the boundary quantum extremal surface result in a simple AdS/BCFT setup.
Context
Island 计算结合引力面积项与量子熵。全息缺陷提供了可同时追踪两类贡献的几何环境。
主要结果
Defect extremal surface 极小化由缺陷量子物质修正的 RT 面；在 AdS/BCFT 例子中，它通过体分解过程重现边界量子极值面结果。
为何重要
它为 island 处方提供具体的全息对应，并给出比较体理论与 brane-world 描述的几何语言。
