Abstract

The I-V characteristics of a 1D Josephson-junction array with charging effect is numerically investigated. The hysteresis loops in the I-V curves show the multiple branch structure. When the coupling between junctions is relatively weak and the Josephson critical current j_c is weakly dependent on the junction site, the number of junctions showing the AC Josephson effect changes by one at the transitions to the nearest-neighbor branches. In this case we obtain the I-V curves quite similar to those observe din single crystals of high-Tc cuprates.
