Abstract
The temporal intermittency of voltage of the single-mass (SM) model and 1D Fukuyama-Lee (FL) model for a charge-density-wave system under the influences of dc electric field and noise is studied by numerical experiment. We show by the SM model how the intermittency of voltage jumps corresponds to the ω −α-law of conductivity at low frequencies. An identification method for the parameters of the SM model is proposed. It is also shown by the FL model that the voltage jump observed in K 0.3MoO 3 can be understood as a temporally chaotic and spatially coherent excitation of localized pulses and its propagation.
