Restoring Velocity Immunity via Dynamic Mirror Compensation in a Large-Area Dual-Atom-Interferometer Gyroscope
Jie Gu, Yin-fei Mao, Zhan-Wei Yao +10
We propose and demonstrate a dynamical mirror compensation scheme to restore velocity immunity in a large-area dual-atom-interferometer gyroscope. In an ideal Mach-Zehnder configur…
Amplitude Modulation Noise Suppression of Dynamic Atom Gravimeters
Wen-Zhang Wang, Jin-Ting Li, Dan-Fang Zhang +9
Dynamic atom gravimeters enable absolute gravity measurements on moving platforms. However, their performance is severely degraded due to the complex dynamic environment. This pape…
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…
Analysis of the Dick Effect for AI-based Dynamic Gravimeter

Atom interferometer (AI)-based dynamic gravimeter enable high-precision absolute gravity measurements, crucial for applications in geophysics, navigation, resource exploration, and…
Compact and robust design of the optical system for cold atom interferometer in space
Danfang Zhang, Jinting Li, Wenzhang Wang +11
The optical system is a complex and precise subsystem for the atom interferometer (AI), especially for those used in field or space applications. Here, we introduce the design of t…
Detection of subsurface structures with a vehicle-based atom gravity gradiometer
Xiaowei Zhang, Jiaqi Zhong, Muyan Wang +10
High-precision mobile gravity gradiometers are very useful in geodesy and geophysics. Atom gravity gradiometers (AGGs) could be among the most accurate mobile gravity gradiometers…
