标题： Quasi-fluxon bubble dynamics in a rapid oscillatory microwave field

摘要： 在本文中，我们数值研究了在快速振荡微波场下，由局部环形力稳定的一个二维准通量子泡的动态特性。 该泡表现出两种明显不同的动态模式。 首先，泡壁的振荡随着微波场频率的增加而线性增大，直到达到截止点，之后它会脱离外部场，恢复其自然振荡频率。 准通量子振荡的幅度与微波场频率的平方成反比。 基于Kapitza方法的简化模型，我们证明了这种动态行为是受快速振荡场作用的谐波势系统的特征。 讨论了微波检测的可能应用。 显示英文摘要

摘要： In this article, we numerically study the dynamics of a two-dimensional quasi-fluxon bubble in an oscillatory regime stabilized by a localized annular force under a rapidly oscillating microwave field. The bubble exhibits two distinctly dynamical regimes. At first, the oscillation of the bubble wall scales up linearly with the microwave field frequency until it reaches a cutoff, after which it detaches from the external field, returning to its natural oscillation frequency. The amplitude of the quasi-fluxon oscillations is inversely proportional to the square of the microwave field frequency. Following a simplified model based on the Kapitza approach, we proved that this dynamical behavior is characteristic of systems with a harmonic potential subjected to a rapidly oscillating field. Possible applications of microwave detection are discussed.
