From the Area under the Bessel Excursion to Anomalous Diffusion of Cold Atoms

Researchers develop a new theory to characterize anomalous spatial diffusion of an ensemble of cold ⁸⁷Rb atoms and single ²⁴Mg⁺ ions in optical lattices. The theory shows how a transition from regular to anomalous diffusion, with a continuous range of anomalous scaling, is obtained with the tuning of the laser intensity.
