Abstract
The effect of impurities on the dynamic properties of the charge density wave (CDW) system is explored through numerical simulations based on the one-dimensional Fukuyama, Lee and Rice (FLR) elastic model of weakly pinned incommensurate CDW. In agreement with previous experimental work, the current density J CDW transported by the sliding CDW and the associated excess conductivity σ CDW are found to obey respectively the laws J CDW ∝ (E/E T−1) α and σ CDW ∝ (E T/E) (E/E T −1 α in a wide range of fields and impurity concentrations; α is an impurities dependent exponent and E T is the threshold field. The spatial mean velocity fluctuations present a pic which broadens with increasing field for E ⪢ E T.
