Optimization of soliton ratchets in inhomogeneous sine-Gordon systems.


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… (More)
