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…
Realization of cold atom gyroscope in space
Jinting Li, Xi Chen, Danfang Zhang +21
High-precision gyroscopes in space are essential for fundamental physics research and navigation. Due to its potential high precision, the cold atom gyroscope is expected to be the…
The space cold atom interferometer for testing the equivalence principle in the China Space Station
Meng He, Xi Chen, Jie Fang +25
The precision of the weak equivalence principle (WEP) test using atom interferometers (AIs) is expected to be extremely high in microgravity environment. The microgravity scientifi…
Absolute frequency measurements with a robust, transportable ^{40}Ca^{+} optical clock
Huaqing Zhang, Yao Huang, Baolin Zhang +9
We constructed a transportable 40Ca+ optical clock (with an estimated minimum systematic shift uncertainty of 1.3*10^(-17) and a stability of 5*10^(-15)/sqrt{tau} ) that can operat…
