Electronic properties of quasi onedimensional conductors with charge density waves (CDW) are peculiar for two reasons. First is related to translational degeneracy of CDW ground state which leads to the phenomena of Fröhlich conductivity1,2. It shows itself in a giant dielectric susceptibility, in nonlinear and nonstationary effects (see proceedings and the reviews3–7). The second reason is related to a strong interaction of CDW deformations with normal electrons, which leads to their fast selftrapping in the course of conversion to various kinds of solitons89. Extensive experimental studies are devoted to the Frölich conductivity (see reviews by Fleming, Gill, Grüner, Jerome, Nad’, Ong, Schlenker et all3–6). At the same time physics of solitons is mainly studied at another substance — polyacetylene1011, where effects of CDW sliding are absent for the case of two-fold commensurability.
