In fact, the quenched disorder in the optically-implemented potential energy landscape drives a transition to instability evolving into microscopic weak chaos with fractional dynamics. As a result, the relation between the space-time selfsimilarity of the system's collective transport properties and its microscopic weak chaos dynamics is revealed.4 pages, 5 figuresSoft Condensed MatterStatistical MechanicsWeak chaos and fractional dynamics in an optically driven colloidal ringtext
