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.

纳米光栅和原子干涉法将用于测量15种原子和分子的静态偶极极化率和货车德瓦尔斯C3系数。极化率的测量将用于检验原子结构计算和提高原子钟的精度。C3测量将测试原子-表面相互作用的计算，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原子物理学的新课程，对学生机械车间工作的支持，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。
