论文摘要
我们表明,在$ ϕ^6 $型号中,Antikink-Kink碰撞中存在厚的光谱墙。在此模型中,它们是由所谓的$ DELACALIZED $ $ $模式$触发的,该$ $ $ $模式$在单soliton行业中不存在,但在Antikink-kink($ \ bar {k} k $)碰撞中触发。因此,光谱壁是一个相当普遍的现象,在许多孤子碰撞中应该发生,涉及非对称扭结,例如,在$ ϕ^8 $或更高的功率模型中。
We show that thick spectral walls exist in antikink-kink collisions in the $ϕ^6$ model. In this model, they are triggered by the so-called $delocalized$ $modes$ which do not exist in the single-soliton sector but emerge in antikink-kink ($\bar{K}K$) collisions. Therefore, spectral walls are a rather common phenomenon that should occur in many solitonic collisions involving non-symmetric kinks as, e.g., in the $ϕ^8$ or higher power models.
