摘要

我们提出了一种利用干涉引力波探测器区分超轻暗物质（ULDM）自旋的新方法。超轻暗物质可以是自旋为 0、1 或 2 的玻色场，每一种都会在信号中产生独特的特征。我们发现，有限时间旅行效应会导致自旋-0 和自旋-1 ULDM 产生主要信号，而自旋-2 则不会。通过使用多个探测器的重叠还原函数（ORF），我们可以区分 ULDM 的自旋。此外，我们还指出，如果考虑到 ORF 上的有限时间光旅行效应，目前对自旋-1 ULDM 与重子耦合常数的约束会减弱 30 倍。

Exploring the spin of ultralight dark matter with gravitational wave detectors

We propose a novel method for distinguishing the spin of ultralight dark matter (ULDM) using interferometric gravitational wave detectors. ULDM can be a bosonic field of spin-0, 1, or 2, and each induces distinctive signatures in signals. We find that the finite-time traveling effect causes a dominant signal for spin-0 and spin-1 ULDM, but not for spin-2. By using overlap reduction functions (ORF) of multiple detectors, we can differentiate between the spins of ULDM. Furthermore, we point out that the current constraint on the coupling constant of spin-1 ULDM to baryons becomes 30 times weaker when the finite-time light-travel effect on the ORF is taken into account.
