Rogue waves in the two dimensional nonlocal nonlinear Schrödinger equation and nonlocal Klein-Gordon equation. [PDF]

open access: yesPLoS ONE, 2018
In this paper, we investigate two types of nonlocal soliton equations with the parity-time (PT) symmetry, namely, a two dimensional nonlocal nonlinear Schrödinger (NLS) equation and a coupled nonlocal Klein-Gordon equation.

Instability of Double-Periodic Waves in the Nonlinear Schrödinger Equation

open access: yesFrontiers in Physics, 2021
It is shown how to compute the instability rates for the double-periodic solutions to the cubic NLS (nonlinear Schrödinger) equation by using the Lax linear equations.

The Coupled Nonlinear Schrödinger Equations Describing Power and Phase for Modeling Phase-Sensitive Parametric Amplification in Silicon Waveguides

open access: yesJournal of Applied Mathematics, 2014
The coupled nonlinear Schrödinger (NLS) equations describing power and phase of the optical waves are used to model phase-sensitive (PS) parametric amplification in a width-modulated silicon-on-insulator (SOI) channel waveguide.

Dispersive Properties of Schrödinger Equations [PDF]

open access: yes, 2005
This thesis mainly concerns the dispersive properties of Schrodinger equations with certain potentials, and some of their consequences. First, we consider the charge transfer models in Rn with n > 2. In this case, the potential is a sum of several

Nonlinear Schrödinger equations and the universal description of dispersive shock wave structure [PDF]

open access: yesStudies in applied mathematics (Cambridge), 2018
The nonlinear Schrödinger (NLS) equation and the Whitham modulation equations both describe slowly varying, locally periodic nonlinear wavetrains, albeit in differing amplitude‐frequency domains.

Completely integrable nonlinear Schrödinger type equations on moving space curves [PDF]

open access: yes, 1997
Using the Lamb formalism, we show that some completely integrable homogeneous and inhomogeneous nonlinear Schrödinger (NLS) type equations such as derivative NLS, extended NLS, higher-order NLS, inhomogeneous NLS, circularly and radially symmetric NLS ...

T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ -deformed nonlinear Schrödinger

open access: yesJournal of High Energy Physics, 2021
The T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ -deformed classical Lagrangian of a 2D Lorentz invariant theory can be derived from the original one, perturbed only at first order by the bare T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ composite field ...

Exact Solutions to a Class of Schamel Nonlinear Equations Modeling Dust Ion-acoustic Waves in Plasma [PDF]

open access: yesAssiut University Journal of Multidisciplinary Scientific Research, 2022
In this paper, we apply the extended Kudryashov method to construct some new exact solitary wave solutions of three important physical models, Schamel-nonlinear Schrödinger (S-NLS) equation, Schamel Korteweg-de Vries (S-KdV) equation, Schamel Korteweg-de

Riemann–Hilbert method and multi-soliton solutions for three-component coupled nonlinear Schrödinger equations

open access: yes, 2019
An integrable three-component coupled nonlinear Schrodinger (NLS) equation is considered in this work. We present the scattering and inverse scattering problems of the three-component coupled NLS equation by using the Riemann-Hilbert formulation ...

Global well-posedness of 2D non-focusing Schrödinger equations via rigorous modulation approximation [PDF]

open access: yes, 2016
We consider the long time well-posedness of the Cauchy problem with large Sobolev data for a class of nonlinear Schrödinger equations (NLS) on R2 with power nonlinearities of arbitrary odd degree.
