Novel Vortex Dynamics in Two-Dimensional Josephson Arrays
Abstract
We present spatially resolved studies of vortex dynamics in two-dimensional Josephson-junction arrays. For bias currents smaller than the array critical current, a small local thermal perturbation at the array boundaries lowers the vortex entry barrier and the array switches to the resistive state. For bias currents slightly above the array critical current, vortices and antivortices are nucleated at opposite edges of the array. All alternating crossing vortex motion is observed experimentally.
