论文摘要
D3-D5相交产生了缺陷CFT，其中量规组的等级在域壁上跳过K单元。本设置映射中本地运算符的单点函数与基础旋转链中的壳状状态与代表D5 Brane的边界状态重叠。我们集中在k = 1的情况下，将构造扩展到gluonic和费米子部门，这对于k> 1而言非常难以实现。作为副产品，我们在扰动理论的半包裹顺序上测试了SU（2）部门中单点函数的全环建议。
A D3-D5 intersection gives rise to a defect CFT, wherein the rank of the gauge group jumps by k units across a domain wall. The one-point functions of local operators in this set-up map to overlaps between on-shell Bethe states in the underlying spin chain and a boundary state representing the D5 brane. Focussing on the k=1 case, we extend the construction to gluonic and fermionic sectors, which was prohibitively difficult to achieve for k>1. As a byproduct, we test an all-loop proposal for the one-point functions in the su(2) sector at the half-wrapping order of perturbation theory.
