On the interpretation of the NbSe3 conductivity in terms of Fröhlich mode motion

Article

A quasi-one-dimensional model with an approximate nesting of the Fermi surfaces is used for the qualitative description of the NbSe3 resistance anomalies. The model reproduces the main features of the increase in resistance near the transition temperature if the Fröhlich mode corresponding to the incommensurate superstructure vector is pinned. In turn, for a completely free (depinned) Fröhlich mode the sliding of the structure removes the singularity in the resistance, which to high accuracy restores the resistance behavior that would correspond to the normal phase. The electron-phonon mechanism of conductivity is assumed near T c . In the region of the residual resistance the relative contributions to the conductivity due to the normal carriers and the sliding Fröhlich mode are investigated. If the ground state in the new phase is of the semimetallic type, the contributions are comparable in magnitudes. It is shown, however, that the interpretation of the resistivity data in terms of the area of the open parts of the Fermi surface is an oversimplification.
