Differential atom interferometry with ${}^{87}$Rb and ${}^{85}$Rb for testing the UFF in STE-QUEST

C Schubert, J Hartwig, H Ahlers +18

In this paper we discuss in detail an experimental scheme to test the universality of free fall (UFF) with a differential ${}^{87}$Rb / ${}^{85}$Rb atom interferometer applicable for e…
