Abstract

The a.c. conductivity of an overdamped one dimensional sine-Gordon system with a low density of kinks is evaluated. This corresponds to a nearly commensurate charge or spin density wave with a kink-lattice representing the deviation from commensurability. The results explain the unusually broad crossover regime of NbSe3 as compared with the similar but more commensurate compound TaS3. When TaS3 becomes commensurate (T {less-than or approximate} 130 K) we predict that its a.c. response increases and its shape slightly sharpens.
