关于BPS系统的几点评论

Some Comments on BPS systems

L. A. Ferreira, P. Klimas, A. Wereszczynski, W. J. Zakrzewski

摘要:

我们看简单的BPS系统涉及一个以上的领域。我们讨论的条件,必须施加在拉格朗日涉及许多领域的各种条款,以产生BPS系统,然后看看在最简单的这种情况下更详细。我们详细分析了BPS系统涉及2相互作用的正弦戈登像字段,无论是当其中一个有一个扭结的解决方案和第二个无论是扭结或antikink解决方案。我们把它们的孤立子静态解,并使用它们作为初始条件,它们在洛伦兹协变版本的这种模型的演变。我们将这些结构发送到它们自己,并发现当它们相互作用较弱时,它们可以通过与它们相互作用强度相关的相移相互传递。当他们互相攻击的时候,他们互相攻击,互相攻击。我们使用的方法修改的梯度流,以可视化的解决方案在空间的领域。

英文摘要:

We look at simple BPS systems involving more than one field. We discuss the conditions that have to be imposed on various terms in Lagrangians involving many fields to produce BPS systems and then look in more detail at the simplest of such cases. We analyse in detail BPS systems involving 2 interacting Sine-Gordon like fields, both when one of them has a kink solution and the second one either a kink or an antikink solution. We take their solitonic static solutions and use them as initial conditions for their evolution in Lorentz covariant versions of such models. We send these structures towards themselves and find that when they interact weakly they can pass through each other with a phase shift which is related to the strength of their interaction. When they interact strongly they repel and reflect on each other. We use the method of a modified gradient flow in order to visualize the solutions in the space of fields.
