A theoretical analysis and determination of the technical requirements for a Bragg diffraction-based cold atom interferometry gravimeter
Qing-Qing Hu, Jun Yang, Yu-Kun Luo +3
We present here a new type of cold atom interferometry gravimeter based on Bragg diffraction, which is able to increase the gravity measurement sensitivity and stability of common…
Scheme for suppressing atom expansion induced contrast loss in atom interferometers
Qing-Qing Hu, Yu-Kun Luo, Ai-Ai Jia +3
The loss of contrast due to atom expansion induced non-perfect Raman pulse area in atom interferometers is investigated systematically. Based on the theoretical simulation, we find…
Observation of vector and tensor light shifts in 87Rb using near-resonant, stimulated Raman spectroscopy
Qing-Qing Hu, Christian Freier, Yuan Sun +5
We present the derivation of the frequency dependent scalar, vector, and tensor dynamical polarizabilities for the two hyperfine levels of the 87Rb atom 5s ground state. Based on t…
Mapping the absolute magnetic field and evaluating the quadratic Zeeman effect induced systematic error in an atom interferometer gravimeter
Qing-Qing Hu, Christian Freier, Bastian Leykauf +4
Precisely evaluating the systematic error induced by the quadratic Zeeman effect is important for developing atom interferometer gravimeters aiming at an accuracy in the regime ( )…
Baseline drift effect on the performance of neutron and gamma ray discrimination using frequency gradient analysis
Guofu Liu, Xiaoliang Luo, Jun Yang +3
Frequency gradient analysis (FGA) effectively discriminates neutrons and gamma rays by examining the frequency-domain features of the photomultiplier tube anode signal. This approa…
