Memory in the photon statistics of multilevel quantum systems
Felipe Caycedo Soler, Ferney J. Rodríguez, G. Zumofen · Physical Review A · 2008
The statistics of photons emitted by single multilevel systems is investigated with emphasis on the nonrenewal characteristics of the photon-arrival times. We consider the correlation between consecutive interphoton times and present closed-form expressions for the corresponding multiple-moment analysis. Based on the moments, a memory measure is proposed which provides an easy way of gauging the nonrenewal statistics. Monte Carlo simulations demonstrate that the experimental verification of nonrenewal statistics is feasible.
