Non-classical spatial and temporal photon correlations

Abstract

We investigate collective emission characteristics of independent sources, having, in particular, relative distances larger than the emission wavelength. By studying the state evolution of the scattered fields in a quantum path picture, we derive and explain quantum optical effects like Dicke superradiance, subradiance, hyperradiance, simultaneous antibunching, bunching and superbunching, as well as generalized Hong-Ou-Mandel interferences or boson sampling in free space.
