• Abstract: We consider theoretically the mechanisms to realize antibunching between the photons scattered on the array of two-level atoms in a general electromagnetic environment. Our goal is the antibunching that persists for the times much longer than the spontaneous emission lifetime of an individual atom. We identify two mechanisms for such persistent antibunching. The first one is based on subradiant states of the atomic array, and the second one does not require any subradiant states. We provided two specific examples of array parameters with optimized antibunching, based on an array in a free space and an array coupled to a waveguide.

  Superradiance and subradiance are collective effects that emerge from coherent interactions between quantum emitters. We use herein a mean-field approach to reduce the complex many-body system to an effective two-atom master equation. We find that three-dimensional and two-dimensional inverted atomic arrays sustain superradiance below a critical lattice spacing.

We also benchmark how these directional emission patterns translate into collective, anisotropic dissipative couplings.
