Optical lattice clocks and their applications in fundamental physics

光晶格原子钟已经实现了10-18量级的系统不确定度和10-19量级的频率稳定度,是下一代“秒”定义的候选装置之一。凭借优异的系统性能,光晶格原子钟逐渐在基础物理研究领域发挥重要作用。文章综述了光晶格原子钟的研究背景、工作原理、关键实验技术及其在基础物理研究等方面的应用。

Optical lattice clocks have achieved a system uncertainty on the level of 10-18 and a frequency stability of 10-19,and are one of the candidate devices for redefinition of the SI second.Benefiting from excellent performance,they are increasingly playing an important role in the field of basic physics research.In this paper,the background,principle,key experimental techniques,and applications of optical lattice clocks in fundamental research are reviewed.
