1305.1714 (Nicolas Mercadier et al.)

Microscopic characterization of Lévy flights of light in atomic vapors    [PDF]

Nicolas Mercadier, Martine Chevrollier, William Guerin, Robin Kaiser
We investigate multiple scattering of near-resonant light in a Doppler-broadened atomic vapor. We experimentally characterize the length distribution of the steps between successive scattering events. The obtained power law is characteristic of a superdiffusive behavior, where rare but very long steps (L\'evy flights) dominate the transport properties.
