论文摘要
我们研究了动态过程，通过该过程，黑洞的标态头发是在理论中生成或分离的，标量场非最少耦合与高斯 - 骨网和RICCI标量不变性。我们集中于远程平衡引力系统的非线性时间演变。在我们的模拟中，我们选择最初的时空是秃头的schwarzschild或标量的球形对称黑洞。将标量场连续积聚到原始黑洞上，系统的最终命运显示出有趣的特征，这些特征取决于初始配置，扰动的优势和特定的度量参数。除标量的过程中，秃头黑洞可以解决标量的头发，我们还观察到动态脱水量，该降水液在连续的标量场吸积后从原始的毛茸茸的孔中去除标量头发。我们通过非线性动力学过程研究了时空的标量场，指标和杂种质量质量的时间演变。
We study dynamic processes through which the scalar hair of black holes is generated or detached in a theory with a scalar field non-minimally coupled to Gauss-Bonnet and Ricci scalar invariants. We concentrate on the nonlinear temporal evolution of a far-from-equilibrium gravitational system. In our simulations, we choose the initial spacetime to be either a bald Schwarzschild or a scalarized spherically symmetric black hole. Succeeding continuous accretion of the scalar field onto the original black hole, the final fate of the system displays intriguing features, which depend on the initial configurations, strengths of the perturbation, and specific metric parameters. In addition to the scalarization process through which the bald black hole addresses scalar hair, we observe the dynamical descalarization, which removes scalar hair from an original hairy hole after continuous scalar field accretion. We examine the temporal evolution of the scalar field, the metrics, and the Misner-Sharp mass of the spacetime and exhibit rich phase structures through nonlinear dynamical processes.
