论文摘要

oscillon是真实标量场的长寿,局部振荡的非线性激发,在通货膨胀后预热期间可以大量产生。我们为Oscillon形成的第一个$(3+1)$ - 维数模拟在预热期间使用非规范动力学术语,例如狄拉克出生的污染形式,发现俄罗斯的形成显着受非规范效应的影响。

Oscillons are long-lived, localized, oscillating nonlinear excitations of a real scalar field which can be abundantly produced during preheating after inflation. We give the first $(3+1)$-dimensional simulation for the oscillon formation during preheating with noncanonical kinetic terms, e.g. the Dirac-Born-Infeld form, and find that the formation of oscillons is significantly influenced by the noncanonical effect.
