Abstract

Mode locking in ac-driven charge-density waves is studied numerically in two and three dimensions, using both continuous equations of motion and a cellular automaton model. As the system size is increased, a complete devils staircase of steps is approached. The fractal dimension of the set of gaps in the staircase is found to be D0=0.750.04 (0.880.05) in two (three) dimensions in the automaton model. The spectrum of singularities f is calculated and is related to the dynamic critical exponent for the charge-density-wave depinning transition.
