论文摘要
在本文中，我们在爱因斯坦重力模型中重新调查了固定的孤子样溶液，并耦合到一个自由且复杂的标量场，这些标量场被称为迷你玻璃星。使用数值方法，我们发现，除了通常的单个微型玻色子溶液外，还有一个新型的解决方案家族，被解释为玻色子恒星的链，该溶液是由沿对称轴的一些玻色恒星制成的。我们显示了两种类型的链的配置，包括偶数数量的成分和奇数成分。此外，我们还研究了复杂标量场对ADM质量$ M $和$ U（1）$ scalar Charge $ q $的频率的影响。有趣的是，玻色子恒星的链的存在不需要引入具有自相互作用潜力的复杂标量场。
In this paper, we re-investigate the stationary, soliton-like solutions in the model of the Einstein gravity coupled to a free and complex scalar field, which have been known as mini-boson stars. With numerical method, we find that in addition to the usual single mini-boson star solution, there exist a novel family of solutions interpreted as chains of boson stars, which is made of some boson stars along the symmetry axis. We show the configuration of two types of chains, including an even number of constituents and an odd number of constituents. Furthermore, we also study the effect of the frequency of the complex scalar field on the ADM mass $M$ and the $U(1)$ scalar charge $Q$. It is interesting to note that the existence of chains of boson stars does not require the introduction of a complex scalar field with self-interacting potential.
