This project will investigate atom guiding in hollow-core fibers and make precision measurements of atomic lifetimes. Atom guiding in the hollow centers of some optical fibers is analogous to light propagation in conventional fiber optics, and may allow a number of fundamental physics tests with atom interferometers similar to experiments with light. Better measurements of atomic lifetimes allow improved understanding of the structure of atoms and fundamental laws of physics such as parity violation. The broader impact of this research is the possibility of development of inertial navigational sensors that are better than GPS and improved understanding of atoms and molecules and their chemistry. Furthermore this research will involve training undergraduate students and military faculty in basic science.

本计画将研究空芯光纤中的原子导引，并精确测量原子寿命。在一些光纤的中空中心中的原子引导类似于传统光纤中的光传播，并且可以允许使用原子干涉仪进行类似于光实验的许多基本物理测试。更好地测量原子寿命可以提高对原子结构和基本物理定律（如宇称破坏）的理解。这项研究的更广泛的影响是开发比GPS更好的惯性导航传感器的可能性，以及提高对原子和分子及其化学的理解。此外，这项研究将涉及对本科生和军事教员进行基础科学培训。
