Multi-photon correlations by interaction with collective Rydberg clouds — •Kevin Kleinbeck and Hans Peter Büchler — University of Stuttgart, Institute for theoretical Physics 3, Stuttgart

Exploiting the Rydberg blockade mechanism, a cold atomic cloud turns into a single effective emitter with collectively enhanced coupling to a focused photonic mode. Verified by experimental results, we give a model Hamiltonian and show that these "Rydberg superatoms" can imprint multi-particle correlations onto initially uncorrelated photons. Especially, we discuss the underlying mechanism for two-photon correlations and show the existence of three-photon correlations even in the connected part of the three-body correlation function.
