Electromagnetically induced transparency of an interacting cold Rydberg ensemble.

Weatherill, K.J. and Pritchard, J.D. and Abel, R.P. and Bason, M.G. and Mohapatra, A.K. and Adams, C.S. (2008) 'Electromagnetically induced transparency of an interacting cold Rydberg ensemble.', Journal of physics B : atomic, molecular and optical physics., 41 (20). p. 201002.

Abstract

We study electromagnetically induced transparency (EIT) of a weakly interacting cold Rydberg gas. We show that for Rydberg states with principal quantum numbers in the range n = 19–26, the onset of interactions is manifest as a depopulation of the Rydberg state. In the limit of a weak probe where the depopulation effect is negligible, we observe no evidence of interaction-induced decoherence and obtain a narrow Rydberg dark resonance with a linewidth of <600 kHz.
