Vacuum state perturbed by an oscillon: composite configurations in ${\varphi }^4$ model

Abstract

We examine the evolution of a vacuum configuration when perturbed by an oscillon. We consider the ${\varphi }^4$ 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.
