Abstract
It is shown that the statistical fluctuations in the distribution of dislocation-adsorbed impurities change the character of the dislocation mobility because of the transition to an anomalous regime of motion of kinks. The characteristics of the corresponding dynamic phase transition are dependent on the interaction between adsorbed impurities, which can either increase or decrease the amplitude of fluctuations in the potential for kinks, depending on the sign of the interaction. The results of the calculations can also be used to describe the kinetics of one-dimensional systems of other physical nature.
