Title: 黑洞的大量玻色子超辐射不稳定性：非线性增长、饱和和引力辐射

Abstract: We study the superradiant instability of a massive boson around a spinning black hole in full general relativity without assuming spatial symmetries. We focus on the case of a rapidly spinning black hole in the presence of a vector boson with a Compton wavelength comparable to the black hole radius, which is the regime where relativistic effects are maximized. We follow the growth of the boson cloud through superradiance into the nonlinear regime as it spins down the black hole, reaches a maximum energy, and begins to dissipate through the emission of gravitational waves. We find that the superradiant instability can efficiently convert a significant fraction of a black hole's rotational energy into gravitational radiation. Show Chinese abstract

Abstract: 我们研究了在不假设空间对称性的完整广义相对论中，围绕旋转黑洞的宏观玻色子的超辐射不稳定性。 我们关注的是在具有与黑洞半径相当的康普顿波长的矢量玻色子存在下，快速旋转黑洞的情况，这是相对论效应最大化的区域。 我们跟踪通过超辐射增长的玻色子云进入非线性区域的过程，随着黑洞自转减慢，能量达到最大值，并开始通过引力波发射而消散。 我们发现，超辐射不稳定性可以有效地将黑洞旋转能量的显著部分转化为引力辐射。
