Abstract

A novel model for a stack of Josephson junctions in which the charging effect of the superconducting layers is properly taken into account has been proposed recently by Koyama and Tachiki. We perform numerical simulations for the I-V characteristics of the model. The hysteresis loops in the I-V curves show the multiple branch structure similar to those observed in single crystals of Bi-2212. We find that the multiple branches are caused by the freezing of the collective longitudinal Josephson plasma modes into the static charge density waves.
