标题： Domain Wall as Cosmological Oscillator

摘要： 在本研究中，我们从宇宙学谐振子的框架出发，考察了畴壁。我们研究了畴壁与周期性背景场之间的相互作用，这可能引起畴壁振荡行为中的扰动。我们提出了一种通过共振振荡现象解决畴壁问题的新机制。当外部驱动力的频率与畴壁的固有频率对齐时，会发生共振振荡。这种同步可以显著放大振荡幅度。如果振荡幅度超过预定的关键变形阈值，畴壁可能会被解构。此外，我们证明了该机制在保持离散对称性的模型中仍然有效。 显示英文摘要

摘要： In this study, we examine the domain wall within the framework of a cosmological harmonic oscillator. We investigate the interaction between the domain wall and a periodic background field, which can induce perturbations in the oscillatory behavior of the wall. We propose a novel mechanism for resolving the domain wall problem through the phenomenon of resonant oscillation. Resonant oscillation occurs when the frequency of the external driving force aligns with the intrinsic frequency of the domain wall. This synchrony can significantly amplify the amplitude of the oscillation. If the amplitude of oscillation exceeds a predetermined critical deformation threshold, the domain wall may be deconstructed. Furthermore, we demonstrate that this mechanism remains valid in models that preserve discrete symmetry.
