Tunable and Robust Long-range Coherent Dipole Interactions Mediated by Weyl Bound States

摘要

We investigate the quantum optical behavior of quantum emitters coupled to a Weyl-like photonic environment. For the single emitter case, we will report on the formation of a novel photon-atom bound state featuring a tunable power-law localization of the excitation around the emitter. When two emitters are considered we show that the emergent bound state can mediate tunable and robust long-range coherent interactions.
