论文摘要
作为一种暗物质候选者，超轻骨化暗物质已受到越来越多的审查，有可能在天文观察中解决难题。我们证明，原子过渡频率比的时间变化的高精度测量可以达到对低质量的超轻轴突样粒子暗物质的敏感性。这些界限是这类暗物质模型的第一个基于实验室的界限。我们提出了进一步的测量，可以增强对超轻轴突样颗粒的敏感性。
Ultralight bosonic dark matter has come under increasing scrutiny as a dark matter candidate that has the potential to resolve puzzles in astronomical observation. We demonstrate that high-precision measurements of time variation in the frequency ratios of atomic transitions achieves leading sensitivity to ultralight axion-like particle dark matter at low masses. These bounds are the first laboratory-based bounds on this class of dark matter models. We propose further measurements that could enhance sensitivity to ultralight axion-like particles.
