Broadband noise in orthorhombic TaS3
We report experimental results on the broadband noise in sliding charge density wave conductor orthorhombic TaS3. We propose that the noise has its origin in the interaction of a deformable condensate with random impurities. The experimental results are in excellent agreement with a phenomenological model based on fluctuations in threshold field due to deformations of the sliding condensate. The amplitude of the noise is directly related to the dynamic coherence volume of these fuctuations.
