The lattice depth is a biperiodic function of time with a zero mean, which realizes a flashing ratchet for matter-wave solitons. We find that the average velocity of a soliton and the soliton current induced by the ratchet depend on the number of atoms in the soliton. As a consequence, soliton transport can be induced through scattering of different solitons. In the regime when matter-wave solitons are narrow compared to the lattice period the dynamics is well described by the effective Hamiltonian theory. © 2008 The American Physical Society.||Source Title:||Physical Review Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/96279||ISSN:||00319007||DOI:||10.1103/PhysRevLett.101.150403|
