Abstract:

Work in three areas is summarized in this report. 1 Two new localized structures were experimentally discovered in vibrating lattices and were described theoretically with a nonlinear Schrodinger equation. One is a domain wall between different types of vibration, the other is a kink in the phase of vibration. The kink has also been discovered in parametrically driven surface waves on water. 2 The direction and spectral energy of interacting nonlinear ocean waves evolve as they approach a sloping beach. A first principles theory was developed for this process and it was shown to agree with ocean experiments. 3 Experiments to determine whether random interacting waves on the ocean move collectively, having average quantities analogous to pressure in a gas as well as collective modes of vibration, are described. wind wave, random waves, nonlinear wave dynamics, soliton, localized structure, kink.
