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…
Interaction effects of pseudospin-based magnetic monopoles and kinks in a doped dipolar superlattice gas
Xiang Gao, Shao-Jun Li, Shou-Long Chen +6
Magnetic monopoles and kinks are topological excitations extensively investigated in quantum spin systems, but usually they are studied in different setups. We explore the conditio…
Quantum metrology with precision reaching beyond- scaling through -probe entanglement generating interactions
Xing Deng, Shou-Long Chen, Mao Zhang +7
Nonlinear interactions are recognized as potential resources for quantum metrology, facilitating parameter estimation precisions that scale as the exponential Heisenberg limit of $…
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…
Testing the Universality of Free Fall at level by Comparing the Atoms in Different Hyperfine States with Bragg Diffraction
Ke Zhang, Min-Kang Zhou, Yuan Cheng +6
We have performed a precision atomic interferometry experiment on testing the universality of free fall (UFF) considering atoms' spin degree of freedom. Our experiment employs the…
Generating scalable entanglement of ultracold bosons in superlattices through resonant shaking
Lushuai Cao, Xing Deng, Qian-Ru Zhu +5
Based on a one-dimensional double-well superlattice with a unit filling of ultracold atoms per site, we propose a scheme to generate scalable entangled states in the superlattice t…
Limits on Lorentz violation in gravity from worldwide superconducting gravimeters
Cheng-Gang Shao, Ya-Fen Chen, Rong Sun +5
We investigated Lorentz violation through anisotropy of gravity using a worldwide array of 12 superconducting gravimeters. The Lorentz-violating signal is extracted from the differ…
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…
Test of the universality of free fall with atoms in different spin orientations
Xiao-Chun Duan, Xiao-Bing Deng, Min-Kang Zhou +7
We report a test of the universality of free fall (UFF) by comparing the gravity acceleration of the Rb atoms in versus that in , where the corresponding sp…
Raman pulse duration effect in gravity gradiometers composed of two atom interferometers
Cheng-Gang Shao, De-Kai Mao, Min-Kang Zhou +4
We investigated the Raman pulse duration effect in a gravity gradiometer with two atom interferometers. Since the two atom clouds in the gradiometer experience different gravitatio…
