sine-Gordon模型中孤子-势系统的集体坐标变量

Collective coordinate variable for soliton-potential system in sine-Gordon model

Kurosh Javidan

摘要:

本文提出了一个集体坐标变量,用于在sine-Gordon模型中加入空间相关势。研究了孤子与δ函数势垒和δ函数势阱的相互作用。大多数相互作用的特征是解析推导出来的。我们将发现,孤子解的行为类似于一个点粒子,它在一个复杂的有效势的影响下运动。有效势是场初始条件和附加势参数的函数。

英文摘要:

A Collective coordinate variable for adding a space dependent potential to the sine-Gordon model is presented. Interaction of solitons with a delta function potential barrier and also delta function potential well is investigated. Most of the characters of interaction are derived analytically. We will find that the behaviour of a solitonic solution is like a point particle which is moved under the influence of a complicated effective potential. The effective potential is a function of the field initial conditions and also parameters of added potential.
