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

Xiao-Chun Duan, Min-Kang Zhou, Xiao-Bing Deng +4

We report a test of the universality of free fall (UFF) related to spin-gravity coupling effects by comparing the gravity acceleration of the ${}^{87}$Rb atoms in $m_F=+1$ versus tha…
