The warped conformal symmetries have been found in the covariant phase space of a set of non-trivial diffeomorphism near the Kerr black hole horizon. In this paper, we consider the retarded Green’s function and the absorption probability for the scalar and higher spin perturbations on a generic non-extreme Kerr black hole background, and perform their holographic calculations in terms of the warped CFT. This provide further evidence on the conjecture that the warped CFT is relevant to the microstate description of the Kerr black hole.

来自扭曲对称性的克尔黑洞的引力辐射

在克尔黑洞视界附近一组非平凡微分同胚的协变相空间中发现了扭曲的共形对称性。在本文中，我们考虑了一般非极端克尔黑洞背景上的延迟格林函数以及标量和高自旋扰动的吸收概率，并根据扭曲的 CFT 进行全息计算。这为扭曲的 CFT 与克尔黑洞的微观状态描述相关的猜想提供了进一步的证据。
