Abstract
The coherent motion in a double junction of Josephson weak links, in which each junction is driven unequally, has been simulated numerically. This unequal driving brings the coupling of two kinds of Josephson frequencies and leads to peculiar phase locking and quasiperiodic motion. The result of current-voltage curves indicates the stable existence of an unequally biased junction voltage state and hysteresis, which reflects the phase locking under the unequal-driving condition.
