Matter-wave gap solitons in atomic band-gap structures.

چکیده
We demonstrate that a Bose-Einstein condensate in an optical lattice forms a reconfigurable matter-wave structure with a band-gap spectrum, which resembles a nonlinear photonic crystal for light waves. We study in detail the case of a two-dimensional square optical lattice and show that this atomic band-gap structure allows nonlinear localization of atomic Bloch waves in the form of two-dimensional matter-wave gap solitons.

Bright Bose-Einstein gap solitons of atoms with repulsive interaction.
We report on the first experimental observation of bright matter wave solitons for 87Rb atoms with repulsive atom-atom interaction. This counterintuitive situation arises inside a weak periodic potential, where anomalous dispersion can be realized at the Brillouin zone boundary. If the coherent atomic wave packet is prepared at the corresponding band edge, a bright soliton is formed inside the ...
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 کاملMobility and interaction of matter-wave solitons in optical lattices
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. Dar...
متن کاملGeneration and detection of matter-wave gap vortices in optical lattices
We analyze numerically the process of dynamical generation of spatially localized vortices in Bose-Einstein condensates BEC’s with repulsive atomic interactions confined by two-dimensional optical lattices. Akin to bright solitons in a repulsive condensate, these nonlinear localized states exist only within the gaps of the matter-wave band-gap spectrum imposed by the periodicity of the lattice ...
متن کاملLocalized gap-soliton trains of Bose-Einstein condensates in an optical lattice.
We develop a systematic analytical approach to study the linear and nonlinear solitary excitations of quasi-one-dimensional Bose-Einstein condensates trapped in an optical lattice. For the linear case, the Bloch wave in the nth energy band is a linear superposition of Mathieu's functions ce_{n-1} and se_{n} ; and the Bloch wave in the nth band gap is a linear superposition of ce_{n} and se_{n} ...
