Atomic density calibration at high-temperature

Erxat Arkin, Jiqing Fu, Qing He, Jia Kong

Abstract

Calibration of atomic density in vapour cell is very important for high precision quantum metrology and fundamental research. Here we propose to use spin noise spectroscopy(SNS) method for density estimation which would be more reliable than the common density estimation methods based on absorption spectrum or thermodynamic equation. We show our test with different density estimation methods, and show the robustness of SNS method.
