Hydrodynamic X-waves

Abstract:

Stationary wave groups exist in a range of nonlinear dispersive media, including optics, Bose-Einstein condensates, plasma, and hydrodynamics. We report experimental observations of nonlinear surface gravity X waves, i.e., X -shaped wave envelopes that propagate over long distances with constant form. These can be described by the 2 D + 1 nonlinear Schrödinger equation, which predicts a balance between dispersion and diffraction when the envelope (the arms of the X ) travel at ± arctan...
