Dynamical Transition in Sliding Charge-density Waves with Quenched Disorder

Condensed Matter 2009-10-28 v1

Abstract

We have studied numerically the dynamics of sliding charge-density waves (CDWs) in the presence of impurities in d=1,2. The model considered exhibits a first order dynamical transition at a critical driving force FcF_c between ``rough'' (disorder dominated) (F<Fc)(F<F_c) and ``flat'' (F>Fc)(F>F_c) sliding phases where disorder is washed out by the external drive. The effective model for the sliding CDWs in the presence of impurities can be mapped onto that of a magnetic flux line pinned by columnar defects and tilted by an applied field. The dynamical transition of sliding CDWs corresponds to the transverse Meissner effect of the tilted flux line.
