摘要：

The effect of disorder on the static and dynamic behavior of one-dimensional charge density waves at low temperatures is studied by analytical and numerical approaches. In the low-temperature region the spatial behavior of the phase-phase correlation function is dominated by disorder but the roughness exponent remains the same as in the pure case. Contrary to high-dimensional systems the dependence of the creep velocity on the electric field is described by an analytic function.
