Conduction noise in sliding charge-density waves

The conduction noise from sliding charge-density waves (CDWs) is studied in NbSe$\sb3$ and K$\sb{0.3}$MoO$\sb3$ (blue bronze). A statistical analysis of the fluctuations in the noise is presented: the probability distributions of the fluctuating spectral components, the power spectra of these fluctuations (i.e. the second spectra), and their correlation functions all indicate that the ac signal accompanying CDW conduction is Gaussian noise. An important consequence of the Gaussian statistics is that the size of the conduction noise is completely characterized by the second moment of its distribution, the rms voltage. This property is instrumental in making reliable measurements of the conduction noise size.
