论文摘要
我们研究了二进制伴侣对远离重力挑战器物理学（GCP）共振频段的轨道频率上黑洞超赞的影响。一个上级状态可以通过伴侣的潮汐扰动将其融入强烈的吸收状态，从而获得抑制的超级利益率。在关键的二元分离以下，这种超高率变为负，并且玻色云被黑洞吸收。这种关键的二元分离导致对GCP的严格限制。尤其是，具有质量比$ q> 10^{ - 3} $的同伴无效所有GCP罚款结构过渡，以及几乎所有的Bohr转换，除了$ |ψ_{211} \ rangle $ state。同时，伴侣的反应表现为作用在二进制上的扭矩，产生浮动/下沉轨道，可以通过脉冲星时间验证。此外，可能终止云生长可能有助于减轻各种无效检测的超轻玻色子质量的当前界限。
We study the impact of a binary companion on black hole superradiance at orbital frequencies away from the gravitational-collider-physics (GCP) resonance bands. A superradiant state can couple to a strongly absorptive state via the tidal perturbation of the companion, thereby acquiring a suppressed superradiance rate. Below a critical binary separation, this superradiance rate becomes negative, and the boson cloud gets absorbed by the black hole. This critical binary separation leads to tight constraints on GCP. Especially, a companion with mass ratio $q>10^{-3}$ invalidates all GCP fine structure transitions, as well as almost all Bohr transitions except those from the $|ψ_{211}\rangle$ state. Meanwhile, the backreaction on the companion manifests itself as a torque acting on the binary, producing floating/sinking orbits that can be verified via pulsar timing. In addition, the possible termination of cloud growth may help to alleviate the current bounds on the ultralight boson mass from various null detections.
