The influence of the dynamic localization on the time dependent oscillations of currents on the one dimensional lattice
The propagation of electrons on the 1D lattice under the influence of dc-ac electric fields is discussed in terms of discretized currents. In the dynamic localization regime the time dependence of such currents gets characterized by regular periodic oscillations. Going beyond dynamic localizations leads, to the onset of aperiodic oscillations. The time dependence of the mean square displacement is also discussed. We found that in the regime of dynamic localization the current and the MSD exhibit the same zero's. Typical plots concerning the time dependence of such oscillations have been displayed.
