Abstract
Nearly commensurate charge density waves are described by a dilute
phase-kink lattice. Linear response analysis shows that the shape of the
AC response depends on the kink density and corresponds to a
distribution of crossover frequencies. For nonlinear response a DC field
EA is defined where the sliding kink lattice reaches the
phason velocity. For E > EA and for some range of fields
and damping constants the sliding system is unstable and the phenomena
of narrow band noise is observed. The results also correspond to unusual
flux lattice dynamics in superconducting films.
