Darboux transformation: new identities [PDF]

open access: yesPhysica Scripta, 2019
Abstract This letter reports some new identities for multisoliton potentials that are based on the explicit representation provided by the Darboux matrix. These identities can be used to compute the complex gradient of the energy content of the tail of the profile with respect to the discrete eigenvalues and the norming constants. The

Construction of angular-dependent potentials from trigonometric Pöschl-Teller systems within the Dunkl formalism

open access: yesActa Polytechnica, 2023
We generate solvable cases of the two angular equations resulting from variable separation in the three-dimensional Dunkl-Schrödinger equation expressed in spherical coordinates.

N-Fold Darboux Transformation for the Classical Three-Component Nonlinear Schrödinger Equations and Its Exact Solutions

open access: yesMathematics, 2021
In this paper, by using the gauge transformation and the Lax pairs, the N-fold Darboux transformation (DT) of the classical three-component nonlinear Schrödinger (NLS) equations is given.

Rational Solutions of a Weakly Coupled Nonlocal Nonlinear Schrödinger Equation

open access: yesAdvances in Mathematical Physics, 2018
In this article, we investigate an integrable weakly coupled nonlocal nonlinear Schrödinger (WCNNLS) equation including its Lax pair. Afterwards, Darboux transformation (DT) of the weakly coupled nonlocal NLS equation is constructed, and then the ...

Darboux–Bäcklund transformations, dressing & impurities in multi-component NLS

open access: yesNuclear Physics B, 2017
We consider the discrete and continuous vector non-linear Schrödinger (NLS) model. We focus on the case where space-like local discontinuities are present, and we are primarily interested in the time evolution on the defect point. This in turn yields the

A Family of Integrable Different-Difference Equations, Its Hamiltonian Structure, and Darboux-Bäcklund Transformation

open access: yesDiscrete Dynamics in Nature and Society, 2018
An integrable family of the different-difference equations is derived from a discrete matrix spectral problem by the discrete zero curvature representation. Hamiltonian structure of obtained integrable family is established.

Solution of High-Order Nonlinear Integrable Systems Using Darboux Transformation

open access: yesAxioms, 2023
The 4×4 trace-free complex matrix set is introduced in this study. By using it, we are able to create a novel soliton hierarchy that is reduced to demonstrate its bi-Hamiltonian structure.

Formal Diagonalisation of Lax-Darboux Schemes

open access: yesМоделирование и анализ информационных систем, 2015
We discuss the concept of Lax-Darboux scheme and illustrate it on well known examples associated with the Nonlinear Schro¨dinger (NLS) equation. We explore the Darboux links of the NLS hierarchy with the hierarchy of Heisenberg model, principal chiral ...
