  A study of bright matter-wave solitons of a cesium Bose-Einstein condensate
(BEC) is presented. Production of a single soliton is demonstrated and
dependence of soliton atom number on the interatomic interaction is
investigated. Formation of soliton trains in the quasi one-dimensional
confinement is shown. Additionally, fragmentation of a BEC has been observed
outside confinement, in free space. In the end a double BEC production setup
for studying soliton collisions is described.
