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学数量的高精度方法的发展不仅导致我们对原子能特性的更好理解，而且还为许多科学技术领域的应用提供了巨大的机会。这样的领域之一是研究原子系统的基本对称性。这项研究的广泛目的是弥合理论和实验奇偶校验在原子中的准确性之间的差距。这些研究的目标是在电动相互作用的标准模型之外寻找新的物理学，并在细胞核中探测违规的均等。对过去所有实验和一些正在进行的实验的解释需要理论计算。为此目的开发了结合两种不同方法的新方法，并且应该能够达到需要精度。这项研究是在原子物理学的界面上，具有高能量物理学，核物理学，量子化学和宇宙学。该项目中开发的方法广泛适用于从研究基本相互作用的研究到未来技术的开发，例如光原子时钟和量子计算。更精确的频率标准标准将为诸如惯性导航，磁力测定法，重力渐变测定法，基本常数测量和物理测试诸如惯性导航，磁力测定法，重力渐变测定法和物理测试等应用的应用开放方法。本项目将涉及对原子物理学研究生的教育。从事该项目的学生将参与最前沿的研究，并接受原子理及其应用方面的教育。
