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.

APS and the Physical Review Editorial Office Continue to Support Researchers

COVID-19 has impacted many institutions and organizations around the world, disrupting the progress of research. Through this difficult time APS and the Physical Review editorial office are fully equipped and actively working to support researchers by continuing to carry out all editorial and peer-review functions and publish research in the journals as well as minimizing disruption to journal access.

We appreciate your continued effort and commitment to helping advance science, and allowing us to publish the best physics journals in the world. And we hope you, and your loved ones, are staying safe and healthy.

Ways to Access APS Journal Articles Off-Campus

Many researchers now find themselves working away from their institutions and, thus, may have trouble accessing the Physical Review journals. To address this, we have been improving access via several different mechanisms. See Off-Campus Access to Physical Review for further instructions.
