Dynamics of matter-wave solitons in a ratchet potential

Poletti, Dario; Alexander, Tristram J; Ostrovskaya, Elena; Li, Baowen; Kivshar, Yuri


We study the dynamics of bright solitons formed in a Bose-Einstein condensate with attractive atomic interactions perturbed by a weak bichromatic optical lattice potential. 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...[Show more]
