Multicomponent solitons in dilute-gas BECs

Dilute-gas Bose-Einstein condensates can host an intriguing variety of nonlinear structures. In effectively one-dimensional geometries, solitonic excitations play a prominent role. While soliton physics in general is very rich, only a limited number of soliton types have been realized in BECs so far. Here we report on the experimental observation of novel types of solitons in multicomponent systems, including the dark-antidark soliton which is related to the recently introduced notion of magnetic solitons in BECs.
