中文摘要 AI 辅助

我们提出利用球-板卡西米尔力测量装置来探测超轻矢量暗物质。我们证明亚皮米级信号可以通过参量放大而变得可探测。我们提出一项新颖的改进,允许连续调谐系统的固有频率,为亚微米尺度开辟新的研究机会。我们表明,改进后的装置能够高精度地确定暗物质质量,显著扩展可探测质量范围,并在$8\times10^{-14}\sim1\times10^{-12}{\rm~ eV}$质量范围内实现迄今最佳灵敏度。

英文摘要

We propose the use of sphere-and-plate Casimir force measurement setups to detect ultralight vector dark matter. We demonstrate that sub-picometer signals can be parametrically amplified to be detectable. We present a novel improvement that allows the continuous tuning of the natural frequency of the system, opening new research opportunities at the submicron scale. We show that the improved setup can determine the dark matter mass with high accuracy, significantly expand the detectable mass range, and achieve the best sensitivity to date in the $8\times10^{-14}\sim1\times10^{-12}{\rm~ eV}$ mass range.
