Dynamic properties of weakly coupled linear chains in two-dimension charge-density-waves (CDW’s) system: A numerical study

•Numerical simulations based the generalized Fukuyama-Lee-Rice model were carried out.•Excess current transported by the sliding CDW’s is reduced in presence of interchain coupling.•The results are discussed in context of the damping mechanisms. In the present letter, the numerical study on the dynamic properties of incommensurate charge-density-waves (CDW’s) in the two-dimensional (2-D) system has been performed by means of the generalized model of Fukuyama-Lee-Rice (FLR). The results showed that the weak interchain interaction effect affects the threshold field and the nonlinear excess current transported by the sliding CDW’s as well as the associated nonlinear excess conductivity. All findings obtained in this work are discussed in the context of damping mechanisms of the collective motion of CDW-condensates.
