本文提出量子黑洞通过发射软引力子耗散无法吸收的能量，从而在振铃谱中产生低频成分和长时标弱通量，为探测量子引力特征提供新途径。
AI中文摘要：
黑洞在并合后的振铃阶段，是揭示新兴引力波中量子引力特征的潜在候选者。在量子理论中，黑洞预期具有离散的面积和能量谱，这与经典视界吸收所有入射扰动的观念相冲突。我们提出，量子黑洞通过发射“软”引力子来耗散其无法吸收的能量，这些引力子带走入射扰动能量与量子跃迁能量之间的差值。我们发现，振铃谱因此富含低频成分，并且存在一个持续时标远长于振铃本身的弱低频通量。
英文摘要：
The ringdown of a black hole following a merger is a potential candidate for revealing the signatures of quantum gravity in the emerging gravitational waves. In quantum theory, black holes are expected to have a discrete area and energy spectrum, which conflicts with the classical notion of an horizon that absorbs all infalling perturbations. We propose that the quantum black hole dissipates the energy it cannot absorb by emitting ``soft'' gravitons that carry away the energy difference between the energy of the infalling perturbation and the quantum transition energy. We find that the ringdown spectrum is consequently enriched with low-frequency components, and that there exists a weak low-frequency flux that persists for a timescale much longer than the ringdown itself.
