Optical transmission of an atomic vapor in the mesoscopic regime.

Peyrot, T. and Sortais, Y. R. P. and Greffet, J.-J. and Browaeys, A. and Sargsyan, A. and Keaveney, J. and Hughes, I. G. and Adams, C. S. (2019) 'Optical transmission of an atomic vapor in the mesoscopic regime.', Physical review letters., 122 (11). p. 113401.


By measuring the transmission of near-resonant light through an atomic vapor confined in a nanocell we demonstrate a mesoscopic optical response arising from the nonlocality induced by the motion of atoms with a phase coherence length larger than the cell thickness. Whereas conventional dispersion theory—where the local atomic response is simply convolved by the Maxwell-Boltzmann velocity distribution—is unable to reproduce the measured spectra, a model including a nonlocal, size-dependent susceptibility is found to be in excellent agreement with the measurements. This result improves our understanding of light-matter interaction in the mesoscopic regime and has implications for applications where mesoscopic effects may degrade or enhance the performance of miniaturized atomic sensors.
