Time-dependent Ginzburg–Landau equation of charge-density-waves and numerical simulation of the sliding

Time-dependent Ginzburg–Landau equation (TDGL) for charge-density-wave (CDW) conductors is discussed. At first, we study a purely one-dimensional case, where the current electrodes are attached from the sides. One of the characteristics of our TDGL is that the non-equilibrium chemical potential for right-moving and left-moving electrons are taken into account as dynamical variables. Then the dynamical interaction between the condensate and the quasiparticles is demonstrated in an apparent form. We present some results of the numerical simulation of the sliding of CDW based on our TDGL. Possible extension to quasi-one dimensional (three-dimensional) systems is also discussed.
