AI 中文摘要
原子干涉仪（AIFs）是高精度惯性传感器，被认为是探测中频带引力波（GWs）及某些暗物质（DM）候选体的有前景仪器。最初，基于AIFs的引力波探测方案被提出用于基线跨度数千公里的空间实验，近期进展表明，基线至少100米的地面装置也可能具备探测引力波的能力。本研究中，我们解析推导了地面探测器的引力波相位响应公式，发现了现有文献中缺失的一项，并通过数值验证了该结果。基于此，我们分析了地面AIF实验的最优几何参数，随后使用开源Python算法对这些优化后的干涉仪的引力波探测方案进行了数值模拟。这类方案的数值模拟目前尚未向学界开放，但对噪声及非平凡引力背景的精确建模至关重要。
英文摘要
Atom interferometers (AIFs) are highly precise inertial sensors and are considered promising instruments for the detection of gravitational waves (GWs) and certain dark matter (DM) candidates in the mid-frequency band. While GW detection with AIFs was initially proposed for space-based experiments with baselines spanning thousands of kilometers, recent developments suggest that terrestrial setups with baselines of at least 100 meters may also be capable of detecting GWs. In this work, we analytically derive the GW phase response formula of a ground detector, find an additional term compared to the existing literature and check it our findings numerically. Based on this treatment, we analyze the optimal geometric parameters for earth-bound AIF experiments. Subsequently, we numerically simulate GW detection schemes for these optimized interferometers using an open-source Python algorithm. Numerical simulations of these schemes have are not available to the community, yet crucial for the accurate modeling of noise and non-trivial gravitational backgrounds.
