论文摘要
在本文中，我们证明了一种被描述为“拓扑通货膨胀”的现象，在拓扑缺陷的核心内发生通货膨胀，有一个非流行的对应物。这出现在一个简单的设置中，该设置包含爱因斯坦重力，耦合到电磁场以及自相互作用的，复杂的价值标量场。该模型的U（1）对称性是不间断的，并导致存在全球规则的溶液，即所谓的玻色子星，该解决方案是为足够强的引力耦合而发展的。我们还发现，与标量头发的黑洞存在相同的现象。
In this paper, we demonstrate that a phenomenon described as "topological inflation" during which inflation occurs inside the core of topological defects, has a non-topological counterpart. This appears in a simple set-up containing Einstein gravity coupled minimally to an electromagnetic field as well as a self-interacting, complex valued scalar field. The U(1) symmetry of the model is unbroken and leads to the existence of globally regular solutions, so-called boson stars, that develop a horizon for sufficiently strong gravitational coupling. We also find that the same phenomenon exists for black holes with scalar hair.
