    "abstract": "This paper presents the first experimental evidence of the transition from\ndynamical localization to delocalization under the influence of a\nquasi-periodic driving on a quantum system. A quantum kicked rotator is\nrealized by placing cold atoms in a pulsed, far-detuned, standing wave. If the\nstanding wave is periodically pulsed, one observes the suppression of the\nclassical chaotic diffusion, i.e. dynamical localization. If the standing wave\nis pulsed quasi-periodically with two different frequencies, dynamical\nlocalization is observed or not, depending on the two frequencies being\ncommensurable or incommensurable. One can thus study the transition from the\nlocalized to the delocalized case as a function of the effective dimensionality\nof the system.",
