Tóm tắt

We report the production of matter-wave solitons in an ultracold lithium-7 gas. The effective interaction between atoms in a Bose-Einstein condensate is tuned with a Feshbach resonance from repulsive to attractive before release in a one-dimensional optical waveguide. Propagation of the soliton without dispersion over a macroscopic distance of 1.1 millimeter is observed. A simple theoretical model explains the stability region of the soliton. These matter-wave solitons open possibilities for future applications in coherent atom optics, atom interferometry, and atom transport.

In the vertical direction a residual astigmatism of the imaging system gives a resolution limit of 16 μm.

Over this distance the change in magnetic field due to the curvature is 0.1 G and therefore the change in the scattering length is negligible (Fig. 2).
