Test of Equivalence Principle at $10^{-8}$ Level by a Dual-species Double-diffraction Raman Atom Interferometer

Lin Zhou, Shitong Long, Biao Tang +9

We report an improved test of the weak equivalence principle by using a simultaneous ${}^{85}$Rb-${}^{87}$Rb dual-species atom interferometer. We propose and implement a four-wave doub…
