Asymptotic Calculation of Discrete Nonlinear Wave Interactions

P. G. Kevrekidis, Avinash Khare, A. Saxena, I. Bena, A. R. Bishop

摘要:

我们用Manton [Nucl.Phys.B150,397(1979)]提出的方法说明如何计算色散方程离散孤立波之间的渐近相互作用。我们还讨论了由于离散性所产生的并发症,并展示了该方法在非线性薛定谔,以及在克莱因-戈登晶格中的应用,找到了良好的协议与直接数值计算。

英文摘要:

We illustrate how to compute asymptotic interactions between discrete solitary waves of dispersive equations, using the approach proposed by Manton [Nucl. Phys. B 150, 397 (1979)]. We also discuss the complications arising due to discreteness and showcase the application of the method in nonlinear Schrodinger, as well as in Klein-Gordon lattices, finding excellent agreement with direct numerical computations.
