Abstract

The topological aspects of the conversion of collective charge density wave transport into the ohmic one in front of extended barriers are discussed in the frame of Gor’kov’s model. It is shown that simultaneous phase slips form a family of dislocation lines. The shape and dynamics of these lines depend on the morphology of the barrier. They influence the amplitude of the narrow band noise, but do not modify its fundamental frequency.
