耦合非线性波方程的复合扭解

Composite-kink solutions of coupled nonlinear wave equations

Hosho Katsura

摘要:

我们得到了描述1+1维两个经典标量场动力学的耦合非线性偏微分方程的精确行波解。解是相邻真空之间的纽结插值。我们计算的经典扭结质量,并表明,它饱和Bogomol'nyi型绑定。我们还提出了更一般的一类模型的精确行波解。示例包括耦合的$ϕ^4$和sine-Gordon模型。

英文摘要:

We obtain exact traveling-wave solutions of the coupled nonlinear partial differential equations that describe the dynamics of two classical scalar fields in 1+1 dimensions. The solutions are kinks interpolating between neighboring vacua. We compute the classical kink mass and show that it saturates a Bogomol'nyi-type bound. We also present exact traveling-wave solutions of a more general class of models. Examples include coupled $ϕ^4$ and sine-Gordon models.
