New Applications for Atom Interferometry with Material Nano-Gratings

纳米光栅和原子干涉计量学将被用来测量15种原子和分子的静态偶极极化率和范德华C3系数。极化率测量将用于测试原子结构计算，并提高原子钟的精度。C3的测量将测试原子-表面相互作用的计算，其中包括核心电子和表面的真实描述。这项工作的更广泛影响包括一门新的原子物理课程，支持学生的机械车间工作，以及培训几名新学生成为基础和应用研究的领导者。这项研究将促进与工业界在光学、纳米技术和太阳能利用方面的合作。

Nano-gratings and atom interferometry will be used to measure static dipole polarizabilities and van der Waals C3 coefficients for 15 species of atoms and molecules. The polarizability measurements will be used to test atomic structure calculations and to improve the accuracy of atomic clocks. The C3 measurements will test calculations of atom-surface interactions that include core electrons and realistic descriptions of surfaces.The broader impacts of this work include a new course in atomic physics, support for student machine shop work, and training several new students to become leaders in basic and applied research. This research will foster collaborations with industry on optics, nanotechnology, and solar energy utilization.
