Observation of dispersive shock waves, solitons, and their interactions in viscous fluid conduits

Michelle D. Maiden, Nicholas K. Lowman, Dalton V. Anderson +2

Dispersive shock waves and solitons are fundamental nonlinear excitations in dispersive media, but dispersive shock wave studies to date have been severely constrained. Here we rep…
