Collisions of matter-wave solitons

JHV Nguyen, P Dyke, D Luo, BA Malomed, RG Hulet - Nature Physics, 2014 - nature.com
Solitons are localized wave disturbances that propagate without changing shape, a result of
a nonlinear interaction that compensates for wave packet dispersion. Individual solitons may …
