Flux flow, pinning, and resistive behavior in superconducting networks
We have studied the behavior of superconducting networks in terms of XY and Coulomb gas models. The dynamics of frustrated Josephson junction arrays has been simulated, and good agreement found with experiment. Results have been explained in terms of a simple picture of vortex excitations. The three dimensional XY model has been simulated, as a model for fluctuation effects in high Tc superconductors. In a simple limit, corresponding to no applied magnetic field, good agreement was found with results obtained by previous methods. The two dimensional classical integer Coulomb gas has been simulated. We find new critical behavior in the dense charge limit, arising from the effects of highly correlated charges.
