摘要:

U(1) 规范 Q 球的半径、电荷和能量等性质在解析上难以刻画。已知规范 Q 球基态与全局 Q 球之间存在一种映射关系,可降低规范 Q 球基态分析的复杂性。将该映射推广到激发态,是确定规范 Q 球其余解空间性质的有力工具。本文探索这一映射关系的推广,以数值和解析方式刻画激发态规范 Q 球解及其性质。激发态规范 Q 球的一个特征是存在最大激发态数目并具有最大尺寸,我们通过映射关系对其作出解析预测。我们表明,在薄壁极限下对电荷和能量的解析近似可推广到激发态规范 Q 球,并讨论这些态的不稳定性类型。

英文摘要:

Properties such as the radius, charge and energy of ${U}(1)$ gauged Q-balls are analytically complicated to characterize. A mapping relation is known between the ground state of gauged Q-balls and global Q-balls that reduces the complexity of the analysis of the ground state of gauged Q-balls. Extending the map to excited states is a powerful tool to determine the properties of the rest of gauged Q-ball solution space. In this article we explore the mapping relation extension to characterize numerically and analytically excited gauged Q-balls solutions and their properties. A feature of excited gauged Q-balls is acquiring a maximum number excited states and having a maximal size, which we analytically predict via the mapping relation. We show that analytical approximations of the charge and energy, in the thin-wall limit, can be extended to excited gauged Q-balls and discuss the types of instabilities of these states.
