用两点函数探测磁力线缺陷

Probing magnetic line defects with two-point functions

Aleix Gimenez-Grau

摘要:

本文研究了Wilson-Fisher $O(N)$模型中的磁力线缺陷。一个强有力的方法来探测系统是考虑混合的两点函数的序参量和能量运营商在存在的缺陷。最近开发的色散关系,使我们能够引导这些混合双折射率领先的顺序在$ε$ -扩展。我们还进行了明确的图解计算,找到完美的协议与引导,我们得出结论,提取新的CFT数据预测的两点函数。

英文摘要:

This paper studies magnetic line defects in the Wilson-Fisher $O(N)$ model. A powerful method to probe the system is to consider mixed two-point functions of the order parameter and the energy operator in the presence of the defect. A recently developed dispersion relation allows us to bootstrap these mixed correlators to leading order in the $ε$-expansion. We also carry out explicit diagrammatic calculations, finding perfect agreement with the bootstrap, and we conclude extracting the new CFT data predicted by the two-point functions.
