Theoretical Analyses

The motion of charged particles on a one-dimensional lattice under the influence of dc-ac electric fields is investigated. Analytic probability propagators in real space have been obtained, taking into account of the long-range intersite interactions. It is found that the effect of dynamic localization and delocalization arises mainly from the coupling of dc fields and ac fields. Various situations for the occurrence of localization and delocalization have been discussed in detail. The theoretical analyses show that such phenomena of dynamic localization and delocalization should be observable.
