dc.description.abstract | Unidirectional motion of solitons can take place, although the applied force has zero average in time, when the spatial symmetry is broken by introducing a potential V x , which consists of periodically repeated cells with each cell containing an asymmetric array of strongly localized inhomogeneities at positions xi. A collective coordinate approach shows that the positions, heights, and widths of the inhomogeneities in that order are the crucial parameters so as to obtain an optimal effective potential Uopt that yields a maximal average soliton velocity. Uopt essentially exhibits two features: double peaks consisting of a positive and a negative peak, and long flat regions between the double peaks. Such a potential can be obtained by choosing inhomogeneities with opposite signs e.g., microresistors and microshorts in the case of long Josephson junctions that are positioned close to each other, while the distance between each peak pair is rather large. These results of the collective variable theory are confirmed by full simulations for the inhomogeneous sine-Gordon system. | es |
