论文摘要
在这项工作中，我们将爱因斯坦 - 马克斯韦 - 斯卡尔模型中的自发标量现象推广到更高的自旋场。结果是一个爱因斯坦 - 马克斯韦 - 矢量模型，其中矢量场通过指数耦合函数非最少耦合到麦克斯韦不变。我们表明，当矢量场具有电场的形式时，后者可以保证相关的无毛定理的规避。与标量对应物不同的是，新的自发矢量化的reissner-nordström（RN）黑洞始终是收费不足的，同时又是偏好的。提出和分析了解决方案的概况和域。
In this work, we generalise the spontaneous scalarization phenomena in Einstein-Maxwell-Scalar models to a higher spin field. The result is an Einstein-Maxwell-Vector model wherein a vector field is non-minimally coupled to the Maxwell invariant by an exponential coupling function. We show that the latter guarantees the circumvention of an associated no-hair theorem when the vector field has the form of an electric field. Different than its scalar counterpart, the new spontaneously vectorized Reissner-Nordström (RN) black holes are, always, undercharged while being entropically preferable. The solution profile and domain of existence are presented and analysed.
