摘要：
We review recent experimental and theoretical work on the creation of bright matter wave solitons in Bose- Einstein condensates. In two recent experiments, solitons are formed from Bose- Einstein condensates of Li-7 by utilizing a Feshbach resonance to switch from repulsive to attractive interactions. The solitons are made to propagate in a one-dimensional potential formed by a focused laser beam. For repulsive interactions, the wavepacket undergoes dispersive wavepacket spreading, while for attractive interactions, localized solitons are formed. In our experiment, a multi-soliton train containing up to ten solitons is observed to propagate without spreading for a duration of 2 s. Adjacent solitons are found to interact repulsively, in agreement with a calculation based on the nonlinear Schrodinger equation assuming that the soliton train is formed with an alternating phase structure. The origin of this phase structure is not entirely clear.
