    "abstract": "We examine the effect of the initial atomic momentum distribution on the\ndynamics of the atom-optical realisation of the quantum kicked rotor. The atoms\nare kicked by a pulsed optical lattice, the periodicity of which implies that\nquasi-momentum is conserved in the transport problem. We study and compare\nexperimentally and theoretically two resonant limits of the kicked rotor: in\nthe vicinity of the quantum resonances and in the semiclassical limit of\nvanishing kicking period. It is found that for the same experimental\ndistribution of quasi-momenta, significant deviations from the kicked rotor\nmodel are induced close to quantum resonance, while close to the classical\nresonance (i.e. for small kicking period) the effect of the quasi-momentum\nvanishes.",
