Coherent dynamics in a five-level atomic system

The coherent control of multi-partite quantum systems presents one the central prerequisites in state-of-the-art information processing. With added benefit inherent high-fidelity detection capability, atomic high-energy internal states, such as metastable noble gas atoms, promote themselves ideal candidates for advancing science fundamental aspects and technological applications. Using laser-cooled neon atoms $^3$P$_2$ state $1s^2 2s^2 2p^5 3s$ (LS-coupling notation) (Racah notation: $^2P_{3/2}\,3s[3/2]_2$) with five $m_F$-sublevels, experimental methods preparation all Zeeman sublevels |m_J> = |+2>, |+1>, |0>, |-1>, |-2> well superposition states five-level system |+2> ... |-2>, three-level two-level |+1> are presented. based on optimized radio frequency laser pulse sequences. evolution is described a simple, semiclassical model. coherence properties prepared studied using Ramsey spin echo measurements.
