Recent advancements in the experimental atomic physics, remarkable increase in computational power, and development of the high-precision methodologies to study atomic physics quantities led not only to our better understanding of the atomic properties but also to remarkable opportunities for applications in many areas of science and technology. One of such areas is the study of fundamental symmetries with atomic systems. The broad aim of this research is to bridge the gap between the accuracy of the theoretical and experimental parity non-conservation studies in atoms. The goals of these studies are to search for new physics beyond the Standard Model of the electroweak interaction and to probe parity violation in the nucleus. Interpretation of all past experiments and some of the ongoing ones requires theoretical calculations. The new method, which combines two different approaches is developed for this purpose and should be able to reach the require precision. This research is at the interface of the atomic physics with high-energy physics, nuclear physics, quantum chemistry, and cosmology. The methods developed in this project are widely applicably to the number of problems ranging from the study of fundamental interactions to the development of future technologies, such as optical atomic clocks and quantum computing. More precise frequency standards will open ways to more sensitive quantum-based standards for applications such as inertial navigation, magnetometry, gravity gradiometry, measurements of the fundamental constants and testing of physics postulates. The present project will involve education of a graduate student in atomic physics. The student working on the project will be involved in the forefront research and educated in atomic physics and its applications.

实验原子物理学的最新进展，计算能力的显着增加，以及研究原子物理量的高精度方法的发展，不仅使我们更好地了解原子的性质，而且还为许多科学和技术领域的应用提供了显着的机会。其中一个领域是研究原子系统的基本对称性。本研究的主要目的是弥合原子宇称非守恒理论研究与实验研究之间的差距。这些研究的目标是寻找新的物理超越标准模型的电弱相互作用和探测宇称破坏的核。对所有过去的实验和一些正在进行的实验的解释需要理论计算。新的方法，它结合了两种不同的方法是为此目的而开发的，应该能够达到所需的精度。该研究处于原子物理与高能物理、核物理、量子化学和宇宙学的接口。该项目开发的方法广泛适用于从基本相互作用研究到未来技术发展（如光学原子钟和量子计算）的许多问题。更精确的频率标准将为更灵敏的量子标准开辟道路，用于惯性导航、磁力测量、重力梯度测量、基本常数测量和物理假设测试等应用。本项目将涉及原子物理学研究生的教育。从事该项目的学生将参与前沿研究，并接受原子物理及其应用方面的教育。
