AI 中文总结

研究暗物质与标量场共形耦合理论中,被赫恩奎斯特暗物质晕包围的黑洞自发标量化现象,通过该理论与晕的天体物理性质,得出标量场构型类量子谱,发现共形耦合常数由晕紧致度参数决定。

AI 中文摘要

我们证明,在暗物质与标量场共形耦合的标量张量理论中,被赫恩奎斯特暗物质晕包围 的黑洞会经历自发标量化,获得非平凡的标量场构型。暗物质晕的天体物理性质直接决定了中心黑洞周围标量场构型的类量子谱。值得注意的是,共形耦合常数变得离散化且仅由晕的紧致度参数决定。

英文摘要

We demonstrate that in a scalar-tensor theory where dark matter is conformally coupled to a scalar field, a black hole surrounded by a Hernquist dark matter halo can undergo spontaneous scalarization, acquiring a nontrivial scalar field configuration. The astrophysical properties of the dark matter halo directly dictate the quantum-like spectrum of scalar field configurations around the central black hole. Remarkably, the conformal coupling constant becomes discretized and is determined solely by the halo's compactness parameter.
