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.

Fermi gases in one dimension: From Bethe ansatz to experiments (2013, background): “In this regime, due to the intrinsic nonlinearity from s-wave scattering between atoms, matter-wave solitons have been observed in several experiments (Becker et al., 2008; Khaykovich et al., 2002; Stellmer et al., 2008; Strecker et al., 2002).”

Solitons in nonlinear lattices (2010, background): “…by the creation of dark solitons of matter waves in BEC with repulsion between atoms (Burger et al., 1999) and, eventually, by the creation of bright 1D matter-wave solitons in BEC with attractive interatomic interactions [Strecker, Partridge, Truscott, and Hulet (2002); Khaykovich et al.

Observation of bright polariton solitons in a semiconductor microcavity (2011, background): “Recent discoveries made with microcavity polaritons include condensation [11, 12], vortices [13, 14], superfluidity [15] and follow a pathway similar to the one which led to the observation of coherent matter wave solitons [5, 6].”
Shortcuts to Adiabaticity (2012, background): “This auxiliary potential can be implemented by means of a blue-detuned laser (Khaykovich et al., 2002) or direct painting with a rapidly moving laser (Milner et al., 2001; Friedman et al., 2001; Henderson et al., 2009).”
Bright matter wave solitons in Bose–Einstein condensates (2003, methodology): “Two groups, one at the Ecole Normale Supérieure in Paris [14] and our group at Rice University [15], have used a Feshbach resonance to create bright matter wave solitons in a BEC”
