Abstract

Neutrons appear to be ideal test particles to search for non-Newtonian gravity at micrometer separations, as with their vanishing electrostatic sensitivity they avoid many of the problems appearing with other test masses. Over the past decade, the qBounce collaboration has developed a technique named gravity resonance spectroscopy (GRS) that allows probing the bound states of ultracold neutrons in the Earth’s gravitational field. With the successful implementation of Ramsey spectroscopy and long interaction times, the setup presented promises to test Einstein’s gravity with unprecedented sensitivity.

超冷中子的拉姆西重力共振光谱

摘要

中子似乎是理想的测试颗粒，可用于在微米间距处寻找非牛顿重力，因为它们消失的静电灵敏度可以避免其他测试质量出现的许多问题。在过去的十年中，q Bounce合作开发了一种称为重力共振光谱（GRS）的技术，该技术可以探测地球引力场中超冷中子的束缚态。随着Ramsey光谱技术的成功实施和较长的相互作用时间，提出的设置有望以前所未有的灵敏度测试爱因斯坦的引力。
