1 May 1996 | Subject: | cond-mat | Affiliation: | Syracuse University), Leon Balents (ITP-UCSB), Matthew P. A. Fisher (ITP-UCSB) and M. Cristina Marchetti (Syracuse University | 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 $F_c$ between ``rough’’ (disorder dominated) $(FF_c)$ 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. | Source: | arXiv, cond-mat/9605007 | Services: | Forum | Review | PDF | Favorites |
