RUI: High-Precision Atomic Structure Measurements and Tests of Fundamental Physics

这项实验研究计划将继续使用激光和原子进行一系列相对较小规模的实验，这些实验将解决有关电弱相互作用以及其他可能违反对称的相互作用的基本物理问题。实验将在对铅等弱电测试具有潜在重要性的原子系统中进行。这些实验利用了半导体激光系统和加热蒸汽室中的铊样品，以及原子束装置。在这些测量的延伸中，铊原子束装置、高压场板和现有的激光系统正被用来进行一种新的实验，以寻找可能的违反时间反转(但保持宇称守恒)的远程相互作用。这种新的实验仪器的原理证明测试已经证明了足够的灵敏度，可以对这类潜在的违反对称性的相互作用设定重要的新限制。该项目的更广泛影响涉及到对高质量本科生研究体验的承诺。

This experimental research program will continue a series of relatively small-scale experiments using lasers and atoms, which will address fundamental questions about physics of the electroweak interaction as well as other possible symmetry-violating interactions. Experiments will be undertaken in atomic systems of potential importance to electroweak tests such as lead. These experiments make use of diode laser systems and thallium samples in heated vapor cells as well as an atomic beam apparatus. In an extension of these measurements, the thallium atomic beam apparatus, high-voltage field plates, and existing laser system are being used to pursue a new experimental search for a possible time-reversal-violating (but parity conserving) long-range interaction. Proof-of-principle tests of this new experimental apparatus have demonstrated sufficient sensitivity to set important new limits on this class of potential symmetry-violating interactions. The broader impact of the program involves the commitment to a quality undergraduate research experience.
