    "abstract": "We study the mechanisms responsible for quantum diffusion in the\nquasiperiodic kicked rotor. We report experimental measurements of the\ndiffusion constant on the atomic version of the system and develop a\ntheoretical approach (based on the Floquet theorem) explaining the\nobservations, especially the ``sub-Fourier\u0027\u0027 character of the resonances\nobserved in the vicinity of exact periodicity, i.e. the ability of the system\nto distinguish two neighboring driving frequencies in a time shorter than the\ninverse of the difference of the two frequencies.",
