论文摘要
我们已经在一个令人惊讶的简单系统中发现了一种新型的标量的带电黑洞：爱因斯坦 - 麦克斯韦 - 克莱恩 - 凯琳 - 戈登场理论，其中三个字段通过horndeski vector-tensor术语非最低限制。除了有毛的带电黑洞外，该系统还展示了Horndeski-Reissner-Nordstrom解决方案和普通的Reissner-Nordstrom，它们将其分叉至标量的解决方案。还有矢量调整的黑洞溶液，尽管它们的度量组件是有限的，但具有中央曲率奇异性，并且具有裸奇异性的溶液，可在周围到处都产生常规的公制组件。我们分析解决方案并介绍其主要特征。
We have discovered a new type of scalarized charged black holes in a surprisingly simple system: an Einstein-Maxwell-Klein-Gordon field theory where the three fields couple non-minimally through a Horndeski vector-tensor term. In addition to hairy charged black holes, this system exhibits Horndeski-Reissner-Nordstrom solutions and ordinary Reissner-Nordstrom ones which bifurcate to the scalarized solutions. There exist also vector-tensor black hole solutions which possess central curvature singularities although their metric components are finite there, and also solutions with naked singularities producing regular metric components everywhere around them. We analyze the solutions and present their main features.
