In-orbit Test of the Weak Equivalence Principle with Atom Interferometry
Dan-Fang Zhang, Jing-Ting Li, Wen-Zhang Wang +22
The Weak Equivalence Principle (WEP) is a central pillar of general relativity. Its precise test with quantum systems in space offers a unique window onto new physics. Here we repo…
Probing new light scalars with the lepton anomalous magnetic moment and the weak equivalence principle violation
Xitong Mei, Dongfeng Gao, Wei Zhao +2
A new scalar particle with generic couplings to the standard-model particles is a possible source for the lepton anomalous magnetic moment and the violation of the weak equivalence…
Frame-dragging effects in a gravitational quantum field theory
Dongfeng Gao, Wei-Tou Ni
Analogous to magnetism in electrodynamics, it is gravitomagnetism in relativistic gravity. Since gravity determines locally inertial frames, in general relativity (GR) and other re…
Terrestrial Very-Long-Baseline Atom Interferometry: Summary of the Second Workshop
Adam Abdalla, Mahiro Abe, Sven Abend +307
This summary of the second Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI) Workshop provides a comprehensive overview of our meeting held in London in April 2024, build…
Constraining the spin-gravity coupling effects to the -level with dual-species atom interferometers
Dongfeng Gao, Lin Zhou, Jin Wang +1
Spin is one fundamental property of microscopic particles. A lot of theoretical work has postulated the possible coupling between spin and gravitation, which could result in the vi…
