Abstract: The rectification of a single file of attracting particles subjected to a lowfrequency ac drive is proposed as a working mechanism for particle shuttling inan asymmetric narrow channel. Increasing the particle attraction results in thefile condensing, as signalled by the dramatic enhancement of the net particlecurrent. Magnitude and direction of the current become extremely sensitive tothe actual size of the condensate, which can then be made to shuttle betweentwo docking stations, transporting particles in one direction, with anefficiency much larger than conventional diffusive models predict.
