Abstract

We study the overdamped phase dynamics of a charge-density wave (CDW) pinned by randomly located impurities fully including the internal degrees of freedom of the CDW. The current-field behavior, the threshold field, and the phase diagram (pinned versus unpinned) are characterized and discussed. The narrow-band noise is computed explicitly for the full many-body problem, and it is found to be of the type observed in Nb
