Multimessenger Search for Exotic Field Emission with a Global Magnetometer Network
利用全球磁强计网络对奇异场发射的多信使搜索
The history of astronomy has shown that advances in sensing methods open up new windows to the Universe and often lead to unexpected discoveries. Quantum sensor networks in combination with traditional astronomical observations are emerging as a novel modality for multimessenger astronomy. Here we develop a generic analysis framework that uses a data-driven approach to model the sensitivity of a quantum sensor network to astrophysical signals as a consequence of beyond-the-standard model (BSM) physics. The analysis method evaluates correlations between sensors to search for BSM signals coincident with astrophysical triggers, such as black hole mergers, supernovae, or fast radio bursts. Complementary to astroparticle approaches that search for particlelike signals (e.g., weakly interacting massive particles), quantum sensors are sensitive to wavelike signals from exotic quantum fields. This analysis method can be applied to networks of different types of quantum sensors, such as atomic clocks, matter-wave interferometers, and nuclear clocks, which can probe many types of interactions between BSM fields and standard model particles. We use this analysis method to carry out the first direct search utilizing a terrestrial network of precision quantum sensors for BSM fields emitted during a black hole merger. Specifically, we use the global network of optical magnetometers for exotic physics (GNOME) to perform a search for exotic low-mass field (ELF) bursts generated in coincidence with a gravitational-wave signal from a binary black hole merger (GW200311_115853) detected by LIGO/Virgo on the March 11, 2020. The associated gravitational wave heralds the arrival of the ELF burst that interacts with the spins of fermions in the magnetometers. This enables GNOME to serve as a tool for multimessenger astronomy. Our search found no significant events and, consequently, we place the first lab-based limits on combinations of ELF production and coupling parameters.

在 Dailey+ 2021 提出把量子传感器网络用作‘奇异场望远镜’、利用天体物理触发信号对齐 ELF 波包的思路之后,本文将其落地为可操作的数据驱动流水线:自适应谱图分块匹配啁啾、过功率粗筛、似然比检验和 Feldman-Cousins 置信带,并以 GW200311_115853 这一黑洞并合事件为真实触发进行了首次地面网络搜索。与 Sen+ 2024 用 GPS 原子钟网络分析 GW170817 时因太阳电子通量干扰而未能给出约束不同,本文在无显著候选后得到了首个实验室尺度的 ELF 产生-耦合参数上限。随着 Afach+ 2023 所述 Advanced GNOME 共磁强计升级以及更多引力波/快速射电暴触发的积累,该方法有望把灵敏度推进到间接天体物理界限之外,并可能发展为无触发全天搜索,使量子传感器网络成为真正可定位的多信使‘望远镜’。
