论文摘要
超轻的轴突样颗粒是动机良好的遗物，可能会构成宇宙学的暗物质和来源异常的时间依赖性磁场。我们使用i-comagnetometer检测器中的贵族 - 气和碱金属原子的核与在自旋交换无自旋弛豫〜（SELF）方向上的comagnetometer检测器中使用轴突样颗粒与中子和质子的偶联报告了新的陆生界。进行一个月的搜索，我们覆盖了$ 1.4 \ times 10^{ - 12} $ ev/$ c^2 $至$ 2 \ $ 2 \ times 10^{ - 10} $ 〜ev/$ c^2 $，并提供了世界领先的限制，这些极限可取代以前的地面构造，并在两个阶段中改善了许多良好的范围。这些是报道的第一个可靠的地面界限，这些界限是质子与轴突状暗物质的耦合，涵盖了其参数空间中的新的未开发的地形。
Ultralight axion-like particles are well-motivated relics that might compose the cosmological dark matter and source anomalous time-dependent magnetic fields. We report on new terrestrial bounds on the coupling of axion-like particles to neutrons and protons using the nuclei of noble-gas and alkali-metal atoms in a comagnetometer detector operating in the Spin-Exchange Relaxation-Free~(SERF) regime. Conducting a month-long search, we cover the mass range of $1.4\times 10^{-12}$ eV/$c^2$ to $2\times 10^{-10}$~eV/$c^2$ and provide world-leading limits which supersede robust astrophysical bounds and improve upon previous terrestrial constraints by up to two orders of magnitudes for many masses within this range. These are the first reliable terrestrial bounds reported on the coupling of protons with axion-like dark matter, covering a new and unexplored terrain in its parameter space.
