摘要: We find mode-locking steps in simulated current-voltage characteristics of ac-driven vortex lattices with random pinning. For low frequencies there is mode locking above a finite ac force amplitude, while for large any small force. This correlated the nature temporal order different regimes absence drive. The mode-locked state frozen solid pinned moving reference frame, and depinning from step shows plastic flow hysteresis.
