A novel class of ultra-precise atomic clocks based on highly-charged ions will be developed. Such clocks hold an intriguing promise of extending the frontiers of precision measurements. Atomic clocks have both practical (navigation, geodesy, and network synchronization) and fundamental applications. Additionally, advanced tools of computational atomic physics will be used to establish powerful constraints on postulated, but so-far undiscovered exotic interactions related to dark matter and dark forces. Such constraints are unique and at the same time complementary to those derived from particle colliders, such as LHC.The research will be carried out in Nevada, one of the EPSCoR (Experimental Program to Stimulate Competitive Research) states, underrepresented in the scientific enterprize. This fulfills one of the strategic goals of the NSF to 'broaden participation and enhance diversity in NSF programs'; research and education of a graduate student partially supported with the goal of 'advancing discovery and understanding while promoting teaching, training, and learning'. The findings will be disseminated through publications in scientific journals, conference presentations, and the Internet.

将开发一类基于高电荷离子的新型超精密原子钟。这种时钟有望扩展精确测量的前沿。原子钟既有实用（导航、大地测量和网络同步）又有基础应用。此外，计算原子物理的先进工具将用于对与暗物质和暗力相关的假定但迄今为止尚未发现的奇异相互作用建立强大的约束。这些限制是独特的，同时也是对大型强子对撞机等粒子对撞机的限制的补充。这项研究将在内华达州进行，该州是 EPSCoR（刺激竞争性研究实验计划）州之一，在科学企业中代表性不足。 这实现了 NSF 的战略目标之一，即“扩大 NSF 项目的参与并增强多样性”；研究生的研究和教育得到部分支持，其目标是“促进发现和理解，同时促进教学、培训和学习”。研究结果将通过科学期刊、会议报告和互联网上的出版物进行传播。
