Abstract

Multiple scattering of the electromagnetic (EM) field from an ensemble of resonators generates interactions which can lead to a cooperative response. In atomic gases, the cooperative response is often washed out due to fluctuations in atomic positions. When these fluctuations are restricted, as in an optical lattice in a Mott-insulator state with precisely one atom per lattice site, a cooperative response can be observed [1]. The ability to fabricate metamaterials whose constituent circuit elements, meta-atoms at fixed positions, interact in prescribed ways with EM fields also permits the construction of systems in which cooperative phenomena emerge.
