Embedded Soliton Solutions: A Variational Study
نویسندگان
چکیده
Embedded solitons(ES) represent solitary waves which reside inside the continuous spectrum of a nonlinear-wave system. This type of solitons was first reported by Yang et al. [1] in optical models characterized by opposing dispersion and competing nonlinearities at fundamental and second harmonics. More specifically, optical media with quadratic χ and cubic χ nonlinear susceptibilities can support ES solutions. The evolution of ES is governed by the coupled nonlinear partial differential equations [2]:

Soliton Solutions Of Nonlinear Partial Differential Equations Using Variational Approximations And Inverse Scattering Techniques
Throughout the last several decades many techniques have been developed in establishing solutions to nonlinear partial differential equations (NPDE). These techniques are characterized by their limited reach in solving large classes of NPDE. This body of work will study the analysis of NPDE using two of the most ubiquitous techniques developed in the last century. In this body of work, the anal...
متن کاملEmbedded Solitons in Lagrangian and Semi-Lagrangian Systems
We develop the technique of the variational approximation for solitons in two directions. First, one may have a physical model which does not admit the usual Lagrangian representation, as some terms can be discarded for various reasons. For instance, the second-harmonic-generation (SHG) model considered here, which includes the Kerr nonlinearity, lacks the usual Lagrangian representation if one...

In this Letter, we study Kaup-Boussinesq system by using the wellknown He’s variational approach. In fact, the He’s variational method is a promising method to various systems of linear and nonlinear equations.
متن کاملVariational solutions for the discrete nonlinear Schrödinger equation
The interaction and propagation of optical pulses in a nonlinear waveguide array is described by the discrete nonlinear Schrödinger equation i∂zψn = −D(ψn+1 + ψn−1 − 2ψn) − γ|ψn|ψn, (1) whereD is a dispersion (or diffraction) coefficient, and γ is a measure of the nonlinearity. By means of the variational approximation, we study the discrete soliton solutions of this equation. We use a trial fu...
متن کاملVariational Method for Studying Solitons in the Korteweg-DeVries Equation
We use a variational method based on the principle of least action to obtain approximate time-dependent single soliton solutions to the KdV equation. A class of trial variational functions of the form u(x, t) = −A(t) exp [ −β(t) |x− q(t)| ] , with n a continuous real variable, is used to parametrize timedependent solutions. We find that this class of trial functions leads to soliton-like soluti...
