标题： Vector Wave Dark Matter and Terrestrial Quantum Sensors

摘要： (超)轻自旋-$1$粒子——暗光子——可以构成全部的暗物质（DM），并且具有超出标准模型的耦合。 这可能导致地面上探测器中依赖于耦合强度的相干、振荡特征。 我们提供了一种信号分析和统计框架，通过考虑（i）底层场的随机性以及（ii）矢量特性，以及（iii）地球自转带来的影响，来推断这种DM的性质。 由于能量均分，在小于相干时间的时间尺度上，DM场矢量通常描绘出一个固定的椭圆。 考虑到这个椭圆和地球的自转，我们强调了傅里叶空间中一种独特的三峰信号，可用于限制DM的耦合强度。 考虑到所有三个峰，我们得出了与纬度无关的这种DM耦合的约束，这与来自单峰研究的约束不同。 我们将我们的框架应用于使用光学机械传感器搜索超轻-$B - L$DM的研究，展示了深入探索这种DM候选者参数空间中此前未被探测区域的能力。 显示英文摘要

摘要： (Ultra)light spin-$1$ particles -- dark photons -- can constitute all of dark matter (DM) and have beyond Standard Model couplings. This can lead to a coherent, oscillatory signature in terrestrial detectors that depends on the coupling strength. We provide a signal analysis and statistical framework for inferring the properties of such DM by taking into account (i) the stochastic and (ii) the vector nature of the underlying field, along with (iii) the effects due to the Earth's rotation. Owing to equipartition, on time scales shorter than the coherence time the DM field vector typically traces out a fixed ellipse. Taking this ellipse and the rotation of the Earth into account, we highlight a distinctive three-peak signal in Fourier space that can be used to constrain DM coupling strengths. Accounting for all three peaks, we derive latitude-independent constraints on such DM couplings, unlike those stemming from single-peak studies. We apply our framework to the search for ultralight $B - L$ DM using optomechanical sensors, demonstrating the ability to delve into previously unprobed regions of this DM candidate's parameter space.
