Numerical simulation study of the charge density wave dynamic properties in the one-dimensional systems

•The results presented by rigid wave model show a smooth discordance with experimental results.•The results obtained by deformable wave model are in good concordance with the experimental results.•We show that the internal degrees of freedom play a capital role in the CDW dynamic properties.

In this work, we present a numerical simulation study of the dynamic properties of the charge density waves (CDW) in one-dimensional system. We present firstly, the results obtained within the classical model where the CDW is assimilated to a rigid particle. While this model explains qualitatively the CDW conductivity field dependence, a smooth discordance with the experimental results is observed. We present also the results obtained in the context of the deformable model where the CDW is considered as a continuum medium in interaction with the randomly distributed impurities in the lattice. The results obtained within this mode are in good concordance with the experimental ones which showing that the internal degrees of freedom play a capital role in the CDW dynamic properties.
