- Abstract
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 η
Rb,K = −1.9 × 10
−7 with a combined standard uncertainty of σ
η= 3.2 × 10
−7. Graphical abstract: [Figure not available: see fulltext.]
