Currentvoltage scaling of a Josephsonjunction array at irrational frustration
Abstract
Numerical simulations of the currentvoltage characteristics of an ordered twodimensional Josephsonjunction array at an irrational flux quantum per plaquette are presented. The results are consistent with a scaling analysis that assumes a zerotemperature vortexglass transition. The thermalcorrelation length exponent characterizing this transition is found to be significantly different from the corresponding value for vortexglass models in disordered twodimensional superconductors. This leads to a current scale where nonlinearities appear in the currentvoltage characteristics decreasing with temperature {ital T} roughly as {ital T}{sup 2} in contrast with the {ital T}{sup 3} behavior expected for disordered models. {copyright} {ital 1996 The American Physical Society.}
