Current-voltage scaling of a Josephson-junction array at irrational frustration
arXiv:cond-mat/9608091 · doi:10.1103/PhysRevB.54.R9655
Abstract
Numerical simulations of the current-voltage characteristics of an ordered two-dimensional Josephson junction array at an irrational flux quantum per plaquette are presented. The results are consistent with an scaling analysis which assumes a zero temperature vortex glass transition. The thermal correlation length exponent characterizing this transition is found to be significantly different from the corresponding value for vortex-glass models in disordered two-dimensional superconductors. This leads to a current scale where nonlinearities appear in the current-voltage characteristics decreasing with temperature roughly as in contrast with the behavior expected for disordered models.
