Solitary Waves on a Continuous Wave Background

Journal of the Physical Society of Japan, 1995
A class of exact solutions of some nonlinear envelope equations is derived by the Hirota bilinear method. These solutions reduce to a plane wave in the far field but generally are not dark solitons. In one asymptotic regime they simplify to solitary waves on a continuous wave background.

Time Reversing Solitary Waves

Physical Review Letters, 2004
We present new results for the time reversal of nonlinear pulses traveling in a random medium, in particular for solitary waves. We consider long water waves propagating in the presence of a spatially random depth. Both hyperbolic and dispersive regimes are considered.

Perturbations of Solitons and Solitary Waves

Studies in Applied Mathematics, 1981
A direct perturbation method is developed to investigate the evolution of solitary waves in the presence of small perturbations. A uniformly valid first order solution is constructed. The method is applied to several nonlinear evolution equations which support solitons or solitary waves.

Solitary surface acoustic waves

Physical Review E, 2004
Solitary acoustic pulses can propagate along the surface of a coated homogeneous and inhomogeneous medium. It is shown how these nonlinear surface acoustic waves evolve out of initial pulselike conditions generated by pulsed laser excitation and how they can be monitored by optical detection. The solitary pulse shapes at the surface are computed on the

Solitary waves in elastic ferromagnets

Physical Review B, 1986
It is shown, on the basis of the continuum equations of the magnetoelasticity of ferromagnetic crystals, that Bloch walls in an infinite crystal and N\'eel walls in a thin elastic film can be represented by ``magnetoelastic'' solitary waves. In the first case the solitary waves are solutions of a simple sine-Gordon equation in which the only alteration

Stability of vector solitary waves

Physical Review A, 1994
The stability of vector solitary waves in birefringent nonlinear dispersive media is considered. It is shown that the vector solitary waves characterized by two peak intensities in one or both polarization components, such as those reported by Christodoulidis and Joseph [Opt. Lett. 13, 53 (1988)] and Tranik and Sipe [Phys. Rev.

Are Solitary Internal Waves Solitons?

Studies in Applied Mathematics, 1998
Results of fully nonlinear numerical simulations of the interaction of two mode‐1 solitary internal waves, both propagating in the same direction, are presented. After the interaction, two solitary internal waves emerge. The large wave is slightly larger than the initial large solitary wave, while the small one is slightly smaller than the initial ...

Solitary waves in dispersive media

Il Nuovo Cimento B, 2004
The problem of solitary-wave propagation in composite elastic material is considered and solved. The linear equations, in the presence of a dispersive propagation law, give rise to nonlinear effects as the breaking-down of the wave into two modes propagating with different phase velocities.
