Transport on a one dimensional asymmetric substrate is studied for the case of short, soft charged dimers, formed by two equal masses carrying charges of opposite sign. The stationary dimer currents are computed as functions of the drive orientation and the dimer parameters. Optimal transport conditions are predicted to depend on the dimer elastic constant, in close agreement with the simulation data. Correspondingly, the rectification dimer currents sustained by low frequency ac drives reveal a rich phenomenology, also investigated in detail.
