Tunable Topologically-protected Super- and Subradiant Boundary States in One-Dimensional Atomic Arrays
Anwei Zhang, Xianfeng Chen, Vladislav V. Yakovlev +1
Single-photon super- and subradiance are important for the quantum memory and quantum information. We investigate one-dimensional atomic arrays under the spatially periodic magneti…
