Klein-Gordon方程Q球解中能量稳定性和扰动研究

摘要

本文研究了一种复标量场模型中的双层Q球解，在解析形式下计算了Q球荷和能量。同时，分析了其能量稳定性质，通过Klein-Gordon方程获得了Q球能量的扰动表达式。另外，还讨论了Q球暗物质产生的物理效应。%The two-layer Q-ball solutions in the complex scalar field model are studied in this paper, and the Q-ball charge and energy are calculated in an analytical form. Meantime, the energy stability is analyzed, and the perturbative expression of Q-ball is obtained by means of Klein-Gordon equation. Moreover, the physical effect of Q-ball dark matter is also discussed.
