论文摘要
我们回顾了有关在四个时空维度中没有空间异构体的静态黑洞存在的最新结果，并提出了其研究的一般框架。这些配置在球形拓扑的地平线上是规则的。确定了允许其存在的两种不同的机制。第一个依赖于黑洞的孤子极限。当孤子没有空间异构体时，黑洞是孤子和地平线之间的非线性结合状态，将继承该特性。第二个与黑洞标量相关，并且存在量子层的零模式，没有球形层周围的异构体。当零模式没有空间异构体时，其非线性延续的反应使标量的黑洞继承了空间连续对称性。讨论了解决方案的许多一般特征以及可能的概括。
We review recent results on the existence of static black holes without spatial isometries in four spacetime dimensions and propose a general framework for their study. These configurations are regular on and outside a horizon of spherical topology. Two different mechanisms allowing for their existence are identified. The first one relies on the presence of a solitonic limit of the black holes; when the solitons have no spatial isometries, the black holes, being a non-linear bound state between the solitons and a horizon, inherit this property. The second one is related to black hole scalarization, and the existence of zero modes of the scalar field without isometries around a spherical horizon. When the zero modes have no spatial isometries, the backreaction of their non-linear continuation makes the scalarized black holes inherit the absence of spatial continuous symmetries. A number of general features of the solutions are discussed together with possible generalizations.
