Integrable Kondo problems
Davide Gaiotto, Ji Hoon Lee, Jingxiang Wu
Abstract
A bstract 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.
