论文摘要
物质波干涉仪具有重力实验的基本应用，例如测试等效原理和重力的量子性质。此外，物质波干涉仪可以用作量子传感器，以测量由外部巨大移动物体引起的局部重力加速度，从而为技术应用提供了贷款。在本文中，我们将建立一个三维模型，以描述来自外部移动对象的重力梯度信号，并理论上使用基于船尾 - gerlach设置的物质波干涉仪研究可实现的敏感性。作为一种应用，我们将考虑度量和曲率（MIMAC）和重力波检测方案的介观干扰[New J. Phys。 22，083012（2020）]，并使用频率分析量化其对重力梯度的敏感性。我们将考虑基于地球的实验和空间碎片附近的物体，并在卫星的接近度中估算物体的最小可检测质量，这是其距离，速度和方向的函数。
Matter-wave interferometers have fundamental applications for gravity experiments such as testing the equivalence principle and the quantum nature of gravity. In addition, matter-wave interferometers can be used as quantum sensors to measure the local gravitational acceleration caused by external massive moving objects, thus lending itself for technological applications. In this paper, we will establish a three dimensional model to describe the gravity gradient signal from an external moving object, and theoretically investigate the achievable sensitivities using the matter-wave interferometer based on the Stern-Gerlach set-up. As an application we will consider the Mesoscopic Interference for Metric and Curvature (MIMAC) and Gravitational wave detection scheme [New J. Phys. 22, 083012 (2020)] and quantify its sensitivity to gravity gradients using frequency-space analysis. We will consider objects near Earth-based experiments and space debris in proximity of satellites and estimate the minimum detectable mass of the object as a function of their distance, velocity, and orientation.
