This work focuses on theoretical aspects of tests of fundamental symmetries with atoms and molecules. The project is driven by searches for new physics, such as supersymmetry, beyond the standard model of elementary particles, with atomic parity violation. Such searches rely on exquisite experimental sensitivity to minute effects of fundamental forces on atomic and molecular structure. High-accuracy calculations are required for revealing (or extracting constraints on) new, yet undiscovered particles. The derived constraints are competitive and, at the same time complementary to the information gained from particle colliders.The broader impacts of this work evidently reach beyond AMO physics, into fundamental elementary particle theory. The impacts are broad, as the work may contribute to extensions of the standard model. In addition, this grant will support research and education of a graduate student. The student will be encouraged to participate at meetings and activities of the American Physical Society. The findings and results will be disseminated through publications in scientific journals, conference presentations, and the Internet.

这项工作侧重于原子和分子基本对称性测试的理论方面。这个项目的动力是寻找新的物理学，比如超对称，超越基本粒子的标准模型，违反原子宇称。这种搜索依赖于对基本力对原子和分子结构的微小影响的精密实验灵敏度。揭示（或提取约束条件）新的、尚未发现的粒子需要高精度的计算。导出的约束条件是相互竞争的，同时与粒子对撞机获得的信息是互补的。这项工作的广泛影响显然超越了AMO物理学，进入基本基本粒子理论。影响是广泛的，因为这项工作可能有助于扩展标准模型。此外，这项资助将支持研究生的研究和教育。学生将被鼓励参加美国物理学会的会议和活动。研究结果和结果将通过科学期刊、会议报告和互联网的出版物进行传播。
