论文摘要
我们讨论了Kondo问题的整合性和墙壁交叉特性,其中一维杂质与2D手性CFT耦合并触发缺陷RG流动。我们回顾了几个新的和古老的示例,灵感来自四维Chern-Simons理论和Aggine Gaudin模型中的构造。
We discuss the integrability and wall-crossing properties of Kondo problems, where an 1d impurity is coupled to a 2d chiral CFT and triggers a defect RG flow. We review several new and old examples inspired by constructions in four-dimensional Chern-Simons theory and by affine Gaudin models.
