With the rapid development of modern atomic clock technology, their unprecedented precision elevates them from timekeeping tools to gravitational potential sensors, thereby fosteri…
Scalar dark matter in space-based gravitational-wave detectors: center-of-mass motion, size breathing, and TDI projection
Rui-Yang Hu, Yuan-Zhi Li, An-Qi Wang +3
Ultralight scalar dark matter can make space-based gravitational-wave detectors respond through both the scalar charge of freely falling test masses and scalar-induced changes of l…
Relativistic formulation for dual one-way Doppler Cancellation Scheme observables for gravitational redshift tests
Cheng-Gang Qin, Tong Liu, Yang Li +5
Gravitational redshift is a fundamental prediction of general relativity and a sensitive probe of possible deviations from it. Motivated by recent progress in optical clocks and sa…
Constraints on violation of Lorentz symmetry with clock-comparison redshift experiments
Cheng-Gang Qin, Yu-Jie Tan, Xiao-Yu Lu +4
Lorentz symmetry is a cornerstone of both the General relativity and Standard Model and its experimental verification deepens our understanding of nature. This paper focuses on the…
Preliminary Sensitivity Study for a Gravitational Redshift Measurement with China's Lunar Exploration Project
Cheng-Gang Qin, Tong Liu, Xiao-Yi Dai +5
General relativity (GR) is a highly successful theory that describes gravity as a geometric phenomenon. The gravitational redshift, a classic test of GR, can potentially be violate…
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…
Constraining Light Scalar Field with Torsion-Balance Gravity Experiments
ChengGang Qin, XiaoYu Lu, BingChen Zhao +5
The light scalar field with a coupling to standard model particles provide a possible source of the dark matter, long-range Yukawa forces or violation of the weak equivalence princ…
Test of Einstein Equivalence Principle by frequency comparisons of optical clocks
ChengGang Qin, YuJie Tan, ChengGang Shao
The Einstein Equivalence Principle (EEP) carries a pivotal role in understanding theory of gravity and spacetime. It guarantees the gravity to be understood as geometric phenomenon…
The TianQin project: current progress on science and technology
Jianwei Mei, Yan-Zheng Bai, Jiahui Bao +103
TianQin is a planned space-based gravitational wave (GW) observatory consisting of three earth orbiting satellites with an orbital radius of about . The satellites w…
Relativistic tidal effects on clock-comparison experiments
Cheng-Gang Qin, Yu-Jie Tan, Cheng-Gang Shao
We consider the relativistic tidal effects on frequency shift of clock-comparison experiments. The relativistic formulation for frequency shift and time transfer is derived in the…
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…
