摘要: We study the resonances of quantum kicked rotor subjected to an extended initial distribution. For primary we obtain dispersion relation for map this system. find analytical dependence statistical moments on shape secondary numerically a similar dependence. This allows us devise condition which produces average angular momentum pointing in preset direction increases with time ratio.
