Abstract
The paper considers the dynamics of a particle in a periodically- spac e- and time-dependent potential under the condition of chaos. In the c lassical approach the distribution function for the particle position is shown to obey a diffusion law. We study the process of diffusion in the quantum case. It is found that quantum interference effects cause an acceleration of diffusion. A charged particle in a standing-wave f ield is shown to be a physical system where the discussed phenomenon m ight be observed.
