We study the fully nonlinear dynamics of the spherically symmetric black hole spontaneous scalarization in Einstein Maxwell scalar theory with coupling function f(ϕ)=ebϕ2, which can transform usual Reissner-Nordström anti–de Sitter (RN-AdS) black holes into hairy black holes. Fixing the Arnowitt-Deser-Misner mass of the system, the initial scalar perturbation will destroy the original RN-AdS black hole and turn it into a spherically symmetric hairy black hole provided that the constant b in the coupling function and the charge of the original black hole are sufficiently large, while the cosmological constant is small enough. In the scalarization process, we observe that the black hole irreducible mass initially increases exponentially, then it approaches to and finally saturates at a finite value. Choosing stronger coupling and larger black hole charge, we find that the black hole mass exponentially grows earlier and it takes longer time for a hairy black hole to be developed and stabilized. We further examine phase structure properties in the scalarization process and confirm the observations in the nonlinear dynamical study.

反德西特时空动态带电黑洞自发标化

我们在具有耦合函数的爱因斯坦麦克斯韦标量理论中研究球对称黑洞自发标量的完全非线性动力学 F(φ)=电子-φ2,它可以将通常的 Reissner-Nordström anti-de Sitter (RN-AdS) 黑洞转化为毛茸茸的黑洞。固定系统的 Arnowitt-Deser-Misner 质量,初始标量扰动将破坏原来的 RN-AdS 黑洞,并把它变成一个球对称的毛状黑洞,条件是常数-在耦合函数和原始黑洞的电荷足够大,而宇宙常数足够小。在标量化过程中,我们观察到黑洞的不可约质量最初呈指数增加,然后趋近并最终在有限值处饱和。选择更强的耦合和更大的黑洞电荷,我们发现黑洞质量指数增长更早,毛状黑洞需要更长的时间发展和稳定。我们进一步检查了标化过程中的相结构特性,并确认了非线性动力学研究中的观察结果。
