Abstract
Vortex motion has been studied for the first time in high-quality, highly underdamped, two-dimensional Josephson-junction arrays, with normal-state junction resistances ranging from 43 Ω to 48 kΩ. Strong similarity is found with the dynamics of the phase in single junctions, e.g., vortices with mass moving in the spatially periodic washboard potential of the 2D array. High-resistance arrays show resistance below 35 mK due to either thermally activated depinning or quantum fluctuations.
