Theoretical investigation of single-photons storage in media with electromagnetically induced transparency — •Gor Nikoghosyan1, Michael Fleischhauer1, Mathew Eisaman2, and Mikhail Lukin2 — 1Technische Universität Kaiserslautern, Germany — 2Harvard University, Cambridge, MA, USA
Recently the storage of narrow bandwidth single photons in a room-temperature ensemble of Rb atoms using electromagnetically induced transparency has been experimentally investigated (M. D. Eisaman, A. Andre, F. Massou, M. Fleischhauer, A. S. Zibrov and M. D. Lukin, Nature 438, 837 (2005)). These experiments verified that the quantum statistics of single photons were preserved under EIT propagation by measuring their second order correlation function. At certain single-photon frequencies, the second order correlation function exhibited an unexpected increase above the classical limit. In the present work we discuss a theoretical model of the single-photon generation and EIT-based propagation that accurately describes such an enhancement in the second-order correlation function, and is in good agreement with experimental observations.
