Matter Wave Soliton Train from a Bose-Einstein Condensate — •Randall G. Hulet — Department of Physics and Astronomy, Rice University, P.O. Box 1892, Houston, TX 77251-1892, USA

We have created a train of bright matter wave solitons from a Bose-Einstein condensate of lithium. Up to ten solitons form by modulational instability when the interatomic interactions are tuned from repulsive to attractive. The solitons propagate in a one-dimensional potential formed from a focused laser beam. Adjacent solitons are observed to strongly repel one another due to destructive wave interference.
