标题： Modulating binary dynamics via the termination of black hole superradiance

摘要： 接近旋转黑洞的超轻玻色子超辐射云为红外粒子物理学提供了有力证据。然而，来自附近双星伴星的潮汐扰动可能会使玻色子云不稳定，甚至终止超辐射。 在这项工作中，我们考虑了超辐射终止对广义双星轨道动力学的反作用，这些轨道由其半正焦弦、偏心率和倾斜角参数化。 我们的分析集中在极端质量比并合（EMRI）系统，并采用周期平均近似法，在牛顿极限下推导出这些双星参数的演化方程。 我们发现，二元系统的演化历史可以通过反作用显著调制，使其向具有降低终止速率的大圆赤道轨道演化。 这一过程即使远离共振带也通常会发生。 因此，我们的工作为未来通过EMRI双星参数统计探测超轻玻色子迈出了第一步。 显示英文摘要

摘要： A superradiant cloud of ultralight bosons near a rotating black hole provides a smoking gun for particle physics in the infrared. However, tidal perturbations from a nearby binary companion can destabilise the boson cloud and even terminate superradiance. In this work, we consider the backreaction of superradiance termination to the dynamics of general binary orbits parametrised by their semi-latus rectum, eccentricity and inclination angle. Our analysis focuses on Extreme Mass Ratio Inspiral (EMRI) systems and employs the period-average approximation to derive evolution equations of these binary parameters in the Newtonian limit. We find that the binary evolution history can be significantly modulated by the backreaction towards large circular equatorial orbits with reduced termination rate. This process can generically happen even away from the resonance bands. Our work therefore serves as a first step towards probing ultralight bosons through the statistics of EMRI binary parameters in the future.
