Counting statistics of collective photon transmissions — •Malte Vogl, Gernot Schaller, and Tobias Brandes — Institut für Theoretische Physik, Technische Universität Berlin,Berlin

We theoretically study cooperative effects in the steady-state transmission of photons through a medium of N radiators. Using methods from quantum transport, we find a cross-over in scaling from N to N2 in the current and to even higher powers of N in the higher cumulants of the photon counting statistics as a function of the tunable source occupation. The effect should be observable for atoms confined within a nano-cell with a pumped optical cavity as photon source.
