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…
