Abstract

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 ηRb,K = −1.9 × 10−7 with a combined standard uncertainty of ση = 3.2 × 10−7.

摘要

我们报告了使用using-钾双物种物质波干涉仪对自由落体的通用性进行的改进测试。我们描述了我们的仪器,并详细介绍了操作钾干涉仪时面临的挑战和解决方案,以及影响我们测量的系统效果。我们的厄缶比产率的测定η RB,K  = -1.9×10 -7与的合成标准不确定度σ η  = 3.2×10 -7
