We examine a simple tabletop experimental setup for probing the inverse-square law of gravity and detecting eventual deviations therefrom. The nature of the setup allows indeed to effectively reach for shorter distances compared to what is allowed by other methods. Furthermore, we show that the same setup could also in principle be used to probe the interaction between gravitomagnetism and the intrinsic angular spin of quantum particles. Moreover, we show that the setup allows to have a gravitationally induced harmonic oscillator, introducing thus the possibility of studying in a novel way the interaction between gravity and quantum particles.

使用量子干涉测试平方反比定律和引力磁的前景

我们检查了一个简单的桌面实验装置，用于探索重力的平方反比定律并检测最终的偏差。与其他方法所允许的相比，设置的性质确实允许有效地达到更短的距离。此外，我们表明，相同的设置原则上也可用于探测引力磁与量子粒子的固有角自旋之间的相互作用。此外，我们表明该设置允许具有重力诱导的谐振子，从而引入了以新颖的方式研究重力和量子粒子之间的相互作用的可能性。
