Quasicharge depinning in bilinear Josephson juncton arrays — •Samuel Wilkinson, Nicolas Vogt, and Jared Cole — Chemical and Quantum Physics, School of Applied Sciences, RMIT University, Melbourne 3001, Australia

Bilinear Josephson junction arrays have been the subject of experimental studies, where interesting threshold, Coulomb drag and current mirror behaviour have been observed. Theoretically, the precise mechanisms are not currently well understood. We have applied the theory of quasicharge depinning, which has previously been successfully in describing linear arrays. Here we present the results of numerical simulations which offer insight into some of the experimentally observed phenomena, and suggests possible new effects which may be observed at high voltages.
