摘要:

我们研究史瓦西黑洞的二次代数特殊微扰(ASPs)。其动力学由广义相对论最一般的代数特殊扭曲真空解在微扰展开至二阶推导得出。遵循这一策略,我们给出了进入动力学方程的轴-轴、极-极和极-轴源项的解析表达式。我们证明这些复杂的非齐次方程可以解析求解,并给出二次ASPs轮廓的显式表达式。正如预期,即使在非线性区域,它们在过去视界和未来视界处都表现出指数增长。我们进一步利用这一结果分析二次零模及其在史瓦西黑洞质量和自旋的二次修正方面的解释。本工作提供了对Couch和Newman原始工作在线性区域之外的直接推广。

英文摘要:

We investigate quadratic algebraically special perturbations (ASPs) of the Schwarzschild black hole. Their dynamics are derived from the expansion up to second order in perturbation of the most general algebraically special twisting vacuum solution of general relativity. Following this strategy, we present analytical expressions for the axial-axial, polar-polar and polar-axial source terms entering in the dynamical equations. We show that these complicated inhomogeneous equations can be solved analytically and we present explicit expressions for the profiles of the quadratic ASPs. As expected, they exhibit exponential growth both at the past and future horizons even in the non-linear regime. We further use this result to analyze the quadratic zero modes and their interpretation in terms of quadratic corrections to mass and spin of the Schwarzschild black hole. The present work provides a direct extension beyond the linear regime of the original work by Couch and Newman.
