Abstract

Abstract In this paper, we investigate the numerical solutions of the cubic nonlinear Schrödinger equation via the exponential cubic B-spline collocation method. Crank–Nicolson formulas are used for time discretization of the target equation. A linearization technique is also employed for the numerical purpose. Four numerical examples related to single soliton, collision of two solitons that move in opposite directions, the birth of standing and mobile solitons and bound state solution are considered as the test problems. The accuracy and the efficiency of the purposed method are measured by max error norm and conserved constants. The obtained results are compared with the possible analytical values and those in some earlier studies.

指数三次b样条有限元法求解Schrödinger方程的数值研究

摘要本文利用指数型三次b样条配点法研究了三次非线性Schrödinger方程的数值解。采用Crank-Nicolson公式对目标方程进行时间离散化。为了达到数值目的，还采用了线性化技术。以单孤子、反方向运动的两个孤子碰撞、静止孤子和运动孤子的产生、束缚态解等4个数值算例作为测试问题。用最大误差范数和守恒常数来衡量该方法的精度和效率。所得结果与可能的分析值和一些早期研究的结果进行了比较。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
