de-Broglie Wavelength Enhanced Weak Equivalence Principle Test for Atoms in Different Hyperfine States

Yao-Yao Xu, Xiao-Bing Deng, Xiao-Chun Duan +4

We report a hyperfine-states related weak equivalence principle (WEP) test which searches for possible WEP violation signal in single atom interferometer. With the ground hyperfine…

Generalized Bloch oscillations of ultracold lattice atoms subject to higher-order gradients

Qian-Ru Zhu, Shou-Long Chen, Shao-Jun Li +3

The standard Bloch oscillation normally refers to the oscillatory tunneling dynamics of quantum particles in a periodic lattice plus a linear gradient. In this work we theoreticall…

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…
