Asymmetrical behaviors of second-order photon correlation functions due to interference effects

Abstract

Cooperative interactions among multiple emitters occur when the inter-particle separations are of the order of the emission wavelength or smaller. Typical cooperative phenomena, like superradiance or subradiance, are taking place in a completely or partially excited multiparticle ensemble. These collective behaviors were observed in a wide range of systems including, respectively, real or artificial atoms, or molecules, highly charged ions, solid state media, etc..
