论文摘要
我们通过使用Rubidium potassium Dual-teces Matter Wave干涉仪报告了对自由下落普遍性的改进测试。我们描述了操作钾干涉仪时相关的设备和细节挑战和解决方案,以及影响我们测量的系统效应。我们对eötvös比率的确定产生了$η_{\,\ text {rb,k}} = - 1.9 \ times10^{ - 7} $,具有$σ_η= 3.2 \ times10^{ - 7} $的组合标准不确定性。
We report on an improved test of the Universality of Free Fall using a rubidium-potassium dual-species matter wave interferometer. We describe our apparatus and detail challenges and solutions relevant when operating a potassium interferometer, as well as systematic effects affecting our measurement. Our determination of the Eötvös ratio yields $η_{\,\text{Rb,K}}=-1.9\times10^{-7}$ with a combined standard uncertainty of $σ_η=3.2\times10^{-7}$.
