论文摘要
本文研究了一个包含$ ϕ^4 $ kinks与费米斯相互作用的模型。费米昂的反反应包括在运动方程式中，这会影响扭结碰撞。我们表明，费米恩场会产生一种可以具有吸引力或排斥的力。此外，我们研究了三种不同的方案，这些情况表现出各种各样的行为，包括在$ ϕ^4 $模型中观察到的通常场景，以及两个支着触点的反射，一次反向共振窗口的反射，一单弹跳共振窗口以及Kink-antikink对的创建。我们还发现证据表明，费米昂可以存储负责能量交换机制的一部分能量。
This paper investigates a model containing $ϕ^4$ kinks interacting with fermions. The fermion back-reaction is included in the equations of motion, which affects the kink-antikink collisions. We show that the fermion field generates a force that can be either attractive or repulsive. Moreover, we investigate three different scenarios, which exhibit a wide variety of behaviors including the usual scenarios observed in the $ϕ^4$ model as well as the formation of two oscillons, reflection without contact, one-bounce resonance windows, and the creation of kink-antikink pairs. We also find evidence that the fermion field can store part of the energy responsible for the energy exchange mechanism.
