周期$φ^{4}$模型中的扭结-反扭结碰撞

Kink-Antikink Collisions in the Periodic $φ^{4}$ Model

M. Mohammadi, R. Dehghani

摘要:

我们借用著名的扭结$φ^4$系统在其两个真空之间的势的形式,并将其重复粘贴到其他区域,以引入周期$φ^4$系统。本文致力于提供一个比较数值研究的两个系统的属性。虽然这两个系统对于扭结(反扭结)解决方案非常相似,但它们通常在整个碰撞过程中表现出不同的行为。例如,它们具有不同的临界速度,碰撞过程中的不同结果,以及它们的准分形结构的不同规则。它们的准分形结构也将在扰动扭结-反扭结碰撞中得到研究。因此,三种类型的散射窗口将被引入相对于入射速度,幅度,和初始相位的内部模式,分别。最后,对两个扭结和一个反扭结之间的碰撞进行了详细的比较研究。

英文摘要:

We borrow the form of potential of the well-known kink-bearing $φ^4$ system in the range between its two vacua and paste it repeatedly into the other ranges to introduce the periodic $φ^4$ system. The paper is devoted to providing a comparative numerical study of the properties of the two systems. Although the two systems are quite similar for a kink (antikink) solution, they usually exhibit different behaviors throughout collisions. For instance, they have different critical velocities, different results during collisions, and a different rule in their quasi-fractal structures. Their quasi-fractal structures will be studied in the disturbed kink-antikink collisions as well. Hence, three types of scattering windows will be introduced with respect to the incoming speed, the amplitude, and initial phase of the internal mode, respectively. Moreover, a detailed comparative study of the collisions between two kinks and one antikink will be done at the end.
