Numerical experiments on the dynamics of two-dimension charge-density-waves (CDW's) system in the presence of the weak interchain interaction effect

Layered charge-density-wave (CDW) materials exhibit a lot of interesting aspects for their potential in a variety of device applications. So, a good understanding of their properties may enable the better development of new devices based on them. We address in this paper a study of the dynamic properties of CDW two-dimension electronic crystal in the presence of weak interchain interaction. This study was done through numerical experiments based on the generalized Fukuyama-Lee-Rice (FLR) model. One of the results of this Letter showed that the time-dependent spatially averaged velocity exhibits the steady-state regime characterized by a series of quasi-periodic fluctuations. Moreover, it was found that the increase in the weak interchain interaction effect reduces the NBN amplitude and normalized excess conductivity. All findings accessed here were discussed in the context of the inhomogeneous nature of CDW's dynamics, damping mechanism as well as the attenuation of phase solitons which are nucleated when the CDW's slide.
