Non-Equilibrium dynamics of charge-density-wave phase modes in K0.3MoO3

We investigate the temperature dependence and non-equilibrium dynamics of the phase-phonon bands in a quasi-one-dimensional charge-density-wave system, blue bronze (K₀.₃MoO₃), using optical-pump terahertz-probe spectroscopy, and interpret the results based on an extended time-dependent Ginzburg-Landau model for the coupled charge-lattice modes.
