Gap solitons in elongated geometries: the one-dimensional Gross-Pitaevskii equation and beyond

A. Muñoz Mateo, V. Delgado, Boris A. Malomed

We report results of a systematic analysis of matter-wave gap solitons (GSs) in three-dimensional self-repulsive Bose-Einstein condensates (BECs) loaded into a combination of a cig…
