摘要

我们首次使用磁悬浮粒子搜索超轻暗物质。一个亚毫米永磁体悬浮在超导阱中，测得力灵敏度为0.2fN/Hz。我们没有发现信号存在的证据，并推导出暗物质在质量范围（1.10360−1.10485）×10−13 eV/c2内与重子和轻子数之差耦合的极限。我们对耦合强度的最严格限制是gB−L > 2.98×10−21。我们提出了POLONAISE（利用悬浮物体探测振荡，用于寻找奇异物理的新型加速度测量）实验，该实验具有短期、中期和长期的升级，将为我们提供广泛质量范围内的领先灵敏度，展示了这种新型量子传感技术在寻找暗物质方面的前景。2025年由美国物理学会出版

First Search for Ultralight Dark Matter Using a Magnetically Levitated Particle

We perform the first search for ultralight dark matter using a magnetically levitated particle. A submillimeter permanent magnet is levitated in a superconducting trap with a measured force sensitivity of 0.2fN/Hz. We find no evidence of a signal and derive limits on dark matter coupled to the difference between baryon and lepton number, B−L, in the mass range (1.10360−1.10485)×10−13 eV/c2. Our most stringent limit on the coupling strength is gB−L≲2.98×10−21. We propose the POLONAISE (Probing Oscillations using Levitated Objects for Novel Accelerometry In Searches of Exotic physics) experiment, which features short-, medium-, and long-term upgrades that will give us leading sensitivity in a wide mass range, demonstrating the promise of this novel quantum sensing technology in the hunt for dark matter.
