Abstract
We study the anisotropic Kondo line defects in products of chiral $SU(2)$ WZW models. We propose an ODE/IM correspondence for the anisotropic Kondo problems by considering the four-dimensional Chern Simons theory in the trigonometric case. We verify the claim both by explicit perturbative calculations in the ultraviolet and by exact WKB analysis in the infrared. In doing so, we derived the infrared dynamics of a large class of anisotropic line defects.

Report
In a previous report I had already stated that I believe the paper is worthy to be published in SciPost Physics, without additional changes. In the revised version typos have been fixed and some useful comments have been included. This has led to an improvement over the original text. It goes without saying that I recommend the work for publication.
