Test of the universality of free fall with atoms in different spin orientations

Xiao-Chun Duan, Xiao-Bing Deng, Min-Kang Zhou +7

We report a test of the universality of free fall (UFF) by comparing the gravity acceleration of the ${}^{87}$Rb atoms in $m_F=+1$ versus that in $m_F=-1$, where the corresponding sp…
