【 摘 要 】

We investigate here electron transport in a tight-binding chain under the action of a time-dependent force field. From the exact results for the mean-squared displacement, we discuss various special cases of zero field, static field, and oscillatory field. The consequent delocalization and localization phenomena make the tight-binding chain a textbook example for studying quantum coherent motion.
