Mobility and interaction of matter-wave solitons in optical lattices
نویسندگان
چکیده
Localization of matter waves in optical lattices is possible due to the balance of nonlinearity and dispersion which is modified by the band-gap spectrum of matter waves in a periodic potential. Nonlinear localization of a Bose-Einstein condensate with repulsive interatomic interactions loaded into a onedimensional (1D) optical lattice can occur in the form of both bright and dark solitons. Dark solitons can form within the bands, and bright solitons within the gaps of the Bloch-wave band-gap spectrum.

We analyze the Floquet-Bloch matter-wave spectrum of Bose-Einstein condensates loaded into single-periodic optical lattices and double-periodic superlattices. In the framework of the Gross-Pitaevskii equation, we describe the structure and analyze the mobility properties of dark matter-wave solitons residing on the background of extended nonlinear Bloch-type states. We demonstrate that interact...
متن کاملInteraction of matter-wave gap solitons in optical lattices
We study the mobility and interaction of gap solitons in a Bose–Einstein condensate (BEC) confined by an optical lattice potential. Such localized wavepackets can exist only in the gaps of the matter-wave band-gap spectrum and their interaction properties are shown to serve as a measure of the discreteness imposed on a BEC by the lattice potential. We show that inelastic collisions of two weakl...
متن کاملMatter-wave soliton control in optical lattices with topological dislocations
We address the concept of guiding and transporting matter-wave solitons along the channels of optical lattices made by interference patterns of beams containing topological wavefront dislocations. The local lattice distortions that occur around the dislocations cause solitons to move along reconfigurable paths, a phenomenon that may be used for controlled all-optical manipulation of Bose-Einste...
متن کاملControlled transport of matter waves in two-dimensional optical lattices.
We propose a method for achieving dynamically controllable transport of highly mobile matter-wave solitons in a driven two-dimensional optical lattice. Our numerical analysis based on the mean-field model and the theory based on the time-averaging approach demonstrate that a fast time-periodic rocking of the two-dimensional optical lattice enables efficient stabilization and manipulation of spa...
متن کاملSoliton dynamics in deformable nonlinear lattices.
We describe wave propagation and soliton localization in photonic lattices, which are induced in a nonlinear medium by an optical interference pattern, taking into account the inherent lattice deformations at the soliton location. We obtain exact analytical solutions and identify the key factors defining soliton mobility, including the effects of gap merging and lattice imbalance, underlying th...
