Theory of plastic flows of CDWs in application to a current conversion

We suggest a theoretical picture for distributions of plastic deformations experienced by a sliding Charge Density Wave in the course of the conversio n from the normal current at the contact to the collective one in the bulk. Several mechanisms of phase slips via creation and proliferation of disloc ations are compared. The results are applied to space resolved X-ray [1,2], multi-contact [3,4] and optical [5] studies. Numerical simulations are com bined with model independent relations.
