Description:
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.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Khaykovich, L -- Schreck, F -- Ferrari, G -- Bourdel, T -- Cubizolles, J -- Carr, L D -- Castin, Y -- Salomon, C -- New York, N.Y. -- Science. 2002 May 17;296(5571):1290-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire Kastler Brossel, Ecole Normale Superieure, 24 rue Lhomond, 75231 Paris Cedex 05, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12016308" target="_blank"〉PubMed〈/a〉
