Monodromy Defects in QFT and Holography

Abstract: With an aim to further quantify non-pertubative defects in quantum field theory, we study two-dimensional magnetic defects in four dimensional SUSY quantum field theories which preserve a two-dimensional superconformal symmetry along the defect. These can be thought of as an infrared limit of a magnetic solenoid. On general grounds such magnetic defects support localized chiral edge states, and in our system we generically preserve a (0,2) supersymmetry. We compute various physical observables such induced currents rotating around the solenoid, as well as central charges of the defect, as a function of the monodromies. Time permitting, we also comment on the analagous case of one dimensional defects in three dimensional QFTs.
