Intensity correlations and mesoscopic fluctuations of diffusing photons in cold atoms
arXiv:cond-mat/0610804 · doi:10.1103/PhysRevLett.98.083601
Abstract
We study the angular correlation function of speckle patterns that result from multiple scattering of photons by cold atomic clouds. We show that this correlation function becomes larger than the value given by Rayleigh law for classical scatterers. These large intensity fluctuations constitute a new mesoscopic interference effect specific to atom-photon interactions, that could not be observed in other systems such as weakly disordered metals. We provide a complete description of this behavior and expressions that allow for a quantitative comparison with experiments.
