Abstract
Dicke superradiance is a landmark of quantum optics. It enables a group of N emitters to interact both collectively and coherently. However, a strict limitation is the separation between the emitters that should be smaller than the wavelength of light restricting its applicability. This limitation can be alleviated using near-zero refractive index materials due to the large wavelength and spatial coherence. We theoretically and numerically demonstrate enhanced extended superradiance using a near-zero metamaterial designs. Ultra-high superradiant decay rate enhancement over distances greater than 13 times the free-space wavelength for both two emitters and many-body configurations of emitters is predicted.
