Bright solitary waves are wavepackets that propagate without dispersion and have been under intense investigation in a variety of settings, including Bose–Einstein condensates (BEC), with a view of realizing a matter-wave interferometer. The authors present experimental and theoretical results on a bright-matter-wave soliton from a BEC, and observe splitting and recombination at a barrier potential enabling them to place constraints on the barrier stability needed to implement soliton interferometry.
