论文摘要
黑洞的超平稳性为窗口提供了一个窗口，进入了轻标度场的动力学及其接近旋转黑洞的相互作用。由于黑洞的旋转，标量场的幅度被放大，从而导致“黑洞炸弹”效应。最近的工作表明，动态Chern-Simons重力中的黑洞具有独特的结构，即“ Chern-Simons盖”，这可能会影响黑洞附近物质的行为。由于这些帽的存在，我们在缓慢旋转的黑洞的背景下研究了动态切尔西姆重力的超沉淀。我们发现，其他模式令人兴奋，并为超级拉力超出了Kerr Black Hole的期望。在研究扰动的超级磁谱时，我们发现Chern-Simons的贡献会导致对所得标量云的角度依赖性的小校正。最后，我们评论潜在的可观察到的后果和未来的调查途径。
Black hole superradiance provides a window into the dynamics of light scalar fields and their interactions close to a rotating black hole. Due to the rotation of the black hole, the amplitude of the scalar field becomes magnified, leading to a "black hole bomb" effect. Recent work has demonstrated that rotating black holes in dynamical Chern-Simons gravity possess unique structures, the "Chern-Simons caps," which may influence the behavior of matter near the black hole. Motivated by the presence of these caps, we study superradiance in dynamical Chern-Simons gravity in the context of a slowly rotating black hole. We find that additional modes are excited and contribute to the superradiance beyond what is expected for a Kerr black hole. Studying the superradiant spectrum of perturbations, we find that the Chern-Simons contributions give rise to small corrections to the angular dependence of the resulting scalar cloud. Finally, we comment on potential observable consequences and future avenues for investigation.
