论文摘要
如果标量场的质量与黑洞的质量之间的耦合非常小，则可能会形成黑洞周围大量标量场的长期构型。在这项工作中，我们分析了自我相互作用在静态黑洞周围长寿命云的分布中的影响。我们认为既有吸引力又令人反感的自我互动。通过在频域中的固定背景上以数字求解klein gordon方程，我们发现与非相互作用的情况相比，准静态状态的空间分布可能更大。我们进行了时间演变，以确定自我交互对构型寿命时间的影响，我们的发现表明自我交互的贡献是亚抑制剂的。
Long-lived configurations of massive scalar fields around black holes may form if the coupling between the mass of the scalar field and the mass of the black hole is very small. In this work we analyze the effect of self-interaction in the distribution of the long-lived cloud surrounding a static black hole. We consider both attractive and repulsive self-interactions. By solving numerically the Klein Gordon equation on a fixed background in the frequency domain, we find that the spatial distribution of quasi stationary states may be larger as compared to the non interacting case. We performed a time evolution to determine the effect of the self-interaction on the life time of the configurations our findings indicate that the contribution of the self-interaction is subdominant.
