Dynamical Localization in Mesoscopic Josephson Junctions.

In this paper we use numerical method to study the quantum effect of dynamical localization in a mesoscopic Josephson junction driven by a periodically external electromagnetic field. We find that the charge is localized effectively for the case when the ratio of the field magnitude and the field frequency is less than a certain value. In this case too the magnitude of the supercurrent remains a constant. [ABSTRACT FROM AUTHOR]
