Dynamics and manipulation of matter-wave solitons in optical superlattices

Abstract:
We study the existence and stability of bright, dark, and gap matter-wave solitons in optical superlattices. Then, using these properties, we show that (time-dependent) "dynamical superlattices" can be used to controllably place, guide, and manipulate these solitons. In particular, we use numerical experiments to displace solitons by turning on a secondary lattice structure, transfer solitons from one location to another by shifting one superlattice substructure relative to the other, and implement solitonic "path- following", in which a matter wave follows the time-dependent lattice substructure into oscillatory motion. © 2005 Elsevier B.V.
