Atoms and molecules can be used as extremely precise tools to unravel deeper physics questions. In this program, the nominee will develop portable atomic clocks, with potential applications in metrology, geodesy and satellite navigation. These clocks could also open up a new way to "see" massive dynamical objects in space, using gravitational waves. As well, the nominee will use confined molecular ions to precisely measure rotation frequencies of molecules, which will shed light on molecular physics and chemistry in space. Techniques will be developed to obtain part-per-trillion precision in frequency measurements, which will impact the development of terahertz communications technology.

原子和分子可以作为非常精确的工具来解开更深层次的物理问题。在这个项目中，被提名人将开发便携式原子钟，在计量学，大地测量学和卫星导航方面具有潜在的应用。这些时钟还可以开辟一种新的方式，利用引力波“看到”太空中的大质量动力学物体。此外，被提名者将使用受限的分子离子来精确测量分子的旋转频率，这将揭示空间中的分子物理和化学。将开发技术以获得万亿分之一的频率测量精度，这将影响太赫兹通信技术的发展。
