TLDR
In this article, an improved test of the Universality of Free Fall using a rubidium-potassium dual-species matter wave interferometer was reported. But their results were limited to the case of the Eotvos ratio.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 Eotvos ratio yields $\eta_{\,\text{Rb,K}}=-1.9\times10^{-7}$ with a combined standard uncertainty of $\sigma_\eta=3.2\times10^{-7}$.read more
