Abstract: The chaotic dynamic behavior of single particle in the tilted optical lattice with periodical modulation is explored,and the effect of chaos on quantum transport is studied under the strong modulating case.The chaos is found to assist quantum tunneling only when the modulation frequency matches with the gradient of lattice;otherwise,the chaos promotes localization.Therefore,the quantum transport of the particle can be manipulated via adjusting periodical modulation.

Key words: chaos;Poincaré, section;periodical modulation ;quantum transport
