Collective dynamics of one-dimensional charge density waves - art. no. 184301

The effect of disorder on the static and dynamic behavior of one-dimensiona l charge density waves at low temperatures is studied by analytical and num erical approaches. In the low-temperature region the spatial behavior of th e phase-phase correlation function is dominated by disorder but the roughne ss exponent remains the same as in the pure case. Contrary to high-dimensio nal systems the dependence of the creep velocity on the electric field is d escribed by an analytic function.
