Fringe-locking method for the weak equivalence principle test by simultaneous dual-species atom interferometers
Xiao-Chun Duan, Xiao-Bing Deng, De-Kai Mao +3
We theoretically investigate the application of the fringe-locking method (FLM) in the dual-species quantum test of the weak equivalence principle (WEP). With the FLM, the measurem…
