一类扰动sine-Gordon方程的孤子解

Towards soliton solutions of a perturbed sine-Gordon equation

Armando D'Anna, Monica De Angelis, Gaetano Fiore

摘要:

本文证明了一类扰动sine-Gordon方程在实直线上或圆上的{ \it精确}行波解(特别是孤子解)的存在性,并对它们进行了分类.方程的摄动由一个常数强迫项和一个线性耗散项组成。这些解是由这些项的能量平衡所允许的,并且可以在实验上观察到,例如在超导体理论中的约瑟夫森效应中,这是方程描述的物理现象之一。

英文摘要:

We give arguments for the existence of {\it exact} travelling-wave (in particular solitonic) solutions of a perturbed sine-Gordon equation on the real line or on the circle, and classify them. The perturbation of the equation consists of a constant forcing term and a linear dissipative term. Such solutions are allowed exactly by the energy balance of these terms, and can be observed experimentally e.g. in the Josephson effect in the theory of superconductors, which is one of the physical phenomena described by the equation.
