Testing Lorentz symmetry with space-based gravitational-wave detectors
Cheng-Gang Qin, Jun Ke, Qin Li +4
Lorentz symmetry (LS), one of the most fundamental physical symmetries, has been extensively studied in the context of quantum gravity and unification theories. Many of these theor…
Light propagation in the field of the N-body system and the application in the TianQin mission
Cheng-Gang Qin, Yu-Jie Tan, Ya-Fen Chen +1
Given the high-precision modern space mission, a precise relativistic modeling of observations is required. By solving the eikonal equation with the post-Newtonian approximation, t…
Combined Search for a Lorentz-Violating Force in Short-Range Gravity Varying as the Inverse Sixth Power of Distance
Cheng-Gang Shao, Ya-Fen Chen, Yu-Jie Tan +6
Precision measurements of the inverse-square law via experiments on short-range gravity provide sensitive tests of Lorentz symmetry. A combined analysis of data from experiments at…
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…
Enhanced sensitivity to Lorentz invariance violations in short-range gravity experiments
Cheng-Gang Shao, Ya-Fen Chen, Yu-Jie Tan +3
Recently, first limits on putative Lorentz invariance violation coefficients in the pure gravity sector were determined by the reanalysis of short-range gravity experiments. Such e…
