Observation of Two-Dimensional Localized Jones-Roberts Solitons in Bose-Einstein Condensates
Observation of Two-Dimensional Localized Jones-Roberts Solitons in Bose-Einstein Condensates
We experimentally generate two-dimensional Jones-Roberts solitons in a three-dimensional atomic Bose-Einstein condensate by imprinting a triangular phase pattern. By monitoring their dynamics we observe that this kind of solitary waves are resistant to both dynamic (snaking) and thermodynamic instabilities, that usually are known to strongly limit the lifetime of dark …
