Inverse problem for an inhomogeneous Schr\"odinger equation [PDF]

open access: yes, 1999
An inverse problem is considered for an inhomogeneous Schr\"odinger equation. Assuming that the potential vanishes outside a finite interval and satisfies some other technical assumptions, one proves the uniqueness of the recovery of this potential from ...

The analytic solutions of Schrödinger equation with Cubic-Quintic nonlinearities

open access: yesResults in Physics, 2018
This paper deals with the nonlinear Schrödinger equation with Cubic-Quintic nonlinearities. After transforming the non-autonomous nonlinear Schrödinger equation into a stationary equation by adopting the BPVK idea, we give the classification of the ...

Analytic solutions of the chiral nonlinear schrödinger equations investigated by an efficient approach

open access: yesInternational Journal of Physical Research, 2019
This paper studies the chiral nonlinear Schrödinger equations, describing a central role in the developments of quantum me-chanics, particularly in the field of quantum Hall effect, where chiral excitations are known to appear. More precisely, in this paper, we acquired new exact solutions of the chiral nonlinear (1+1) and (1+2)-dimensional Schrà ...

An algorithm for fractional Schrödinger equation in case of Morse potential

open access: yesAIP Advances, 2020
Based on methods of numerical integration and Riemann–Liouville definition of the fractional derivatives, we find a numerical algorithm to find solutions of the time independent fractional Schrödinger equation for Morse potential or the quantum ...

Higher-order integrable evolution equation and its soliton solutions [PDF]

open access: yes, 2014
We consider an extended nonlinear Schrödinger equation with higher-order odd and even terms with independent variable coefficients. We demonstrate its integrability, provide its Lax pair, and, applying the Darboux transformation, present its first and ...

Multiple Breathers on a Vortex Filament [PDF]

open access: yes, 2014
In this paper we investigate the correspondence between the Da Rios-Betchov equation, which appears in the three-dimensional motion of a vortex filament, and the nonlinear Schrödinger equation.

Approximate Nonlocal Symmetries for a Perturbed Schrödinger Equation with a Weak Infinite Power-Law Memory

open access: yesAppliedMath, 2022
A nonlocally perturbed linear Schrödinger equation with a small parameter was derived under the assumption of low-level fractionality by using one of the known general nonlocal wave equations with an infinite power-law memory.
