摘要

我们研究了受振荡扰动时真空结构的演化。我们只考虑具有单个标量字段的ϕ4场景。对于高激振子，我们发现了新的复合解。它们由多个反扭结-扭结对和一个中心回忆振荡组成。整个过程产生了一个共振结构，其模式类似于真正的扭结-反扭结散射。然后，我们用一个由扭结-反扭结对构成的块状轮廓来近似初始振子。我们对先前得到的数值结果进行了映射。这里提出的发展可能有助于理解振荡衰变再现扭结-反扭结碰撞的典型结构的机制。

Vacuum state perturbed by an oscillon: Composite configurations in ϕ4 model

We examine the evolution of a vacuum configuration when perturbed by an oscillon. We consider the

ϕ^{4}

scenario with a single scalar field only. For highly excited oscillons, we find that new composite solutions appear. They are formed by multiple antikink-kink pairs and a centered reminiscent oscillon. The overall process gives rise to a resonant structure whose pattern resembles that of a genuine kink-antikink scattering. We then approximate the initial oscillon by a lumplike profile constructed as a kink-antikink pair. We map the numerical results previously obtained. The developments proposed here may contribute to the understanding of the mechanism through which an oscillon decay reproduces the structure typically related to a kink-antikink collision.
