Anderson localization VS chiral coupling in waveguide QED setup

In this talk, I will present the recent studies on a one-dimensional array of quantum emitters asymmetrically coupledthrough a waveguiding mode. We will report how disorder, which is an interferometric effect, and unidirectional coupling, which kills the interference, compete with each other in forming and destroying Anderson localized states. We believe that our findings are important for the rapidly developing field of waveguide quantum electrodynamics, where the chiral interactions and disorder play a critical role.
