超冷中子（UCN）是重力精确测试中的强大探针。由于它们的电荷、介电矩和极化率可以忽略不计，它们自然地回避了用原子或宏观测试体进行引力实验所遇到的一些问题。利用这一事实，qBounce合作开发了一种技术-重力共振光谱（GRS）-来研究UCN在地球重力场中的束缚量子态。该技术被用作在微米尺度上搜索假设的非牛顿引力的高精度工具。在本文中，我们描述了最近委托拉姆齐型GRS设置，给出了一个明确的原则证明，并讨论了可能的测量，将执行。
Ultracold neutrons (UCNs) are formidable probes in precision tests of gravity. With their negligible electric charge, dielectric moment, and polarizability they naturally evade some of the problems plaguing gravity experiments with atomic or macroscopic test bodies. Taking advantage of this fact, the qBounce collaboration has developed a technique – gravity resonance spectroscopy (GRS) – to study bound quantum states of UCN in the gravity field of the Earth. This technique is used as a high-precision tool to search for hypothetical Non-Newtonian gravity on the micrometer scale. In the present article, we describe the recently commissioned Ramsey-type GRS setup, give an unambiguous proof of principle, and discuss possible measurements that will be performed.
