Plastic flow of persistent currents in two dimensional strongly interacting systems
arXiv:cond-mat/9804204 · doi:10.1103/PhysRevB.57.R15076
Abstract
The local persistent current in two dimensional strongly interacting systems is investigated. As the interaction strength is enhanced the current in the sample undergoes a transition from diffusive to ordered flow. The strong interacting flow has the characteristics of a plastic flow through dislocations in the pinned charge density wave which develops in the system at low densities.
