Collective shuttling of attracting particles in asymmetric narrow channels

, : Collective shuttling of attracting particles in asymmetric narrow channels. Physical Review. E, Statistical, Nonlinear, and Soft Matter Physics 82(3 Pt 1): 030401-030401

The rectification of a single file of attracting particles subjected to a low frequency ac drive is proposed as a working mechanism for particle shuttling in an asymmetric narrow channel. Increasing the particle attraction results in the file condensing, as signaled by the dramatic enhancement of the net particle current. The magnitude and direction of the current become extremely sensitive to the actual size of the condensate, which can then be made to shuttle between two docking stations, transporting particles in one direction, with an efficiency much larger than conventional diffusive models predict.
