高电荷态离子作为高精度光学原子钟的基础
Highly-charged ions as a basis of optical atomic clockwork of exceptional accuracy
摘要:
提出了一种基于高电荷态离子的新型原子钟。我们考虑了高电荷态离子的$4f^{12}$基态组态中的高禁戒激光可及跃迁。我们对系统效应的评估表明,这些跃迁可用于建造非常精确的原子钟,它可能与最近提出的核钟在精度上竞争。
英文摘要:
We propose a novel class of atomic clocks based on highly charged ions. We consider highly-forbidden laser-accessible transitions within the $4f^{12}$ ground-state configurations of highly charged ions. Our evaluation of systematic effects demonstrates that these transitions may be used for building exceptionally accurate atomic clocks which may compete in accuracy with recently proposed nuclear clock.
