Precision measurements in molecules have advanced rapidly in recent years through developments in techniques to cool, trap, and control. The complexity of molecules makes them a challenge to study, but also offers opportunities for enhanced sensitivity to many interesting effects. Polyatomic molecules offer additional complexity compared to diatomic molecules, yet are still ‘simple’ enough to be laser-cooled and controlled. While laser cooling molecules is still a research frontier itself, there are many proposed and ongoing experiments seeking to combine the advanced control enabled by ultracold temperatures with the intrinsic sensitivity of molecules. In this perspective, we discuss some applications where laser-cooled polyatomic molecules may offer advantages for precision measurements of fundamental physics, both within and beyond the Standard Model.

多原子分子作为基础物理学的量子传感器

近年来，随着冷却，捕获和控制技术的发展，分子的精确测量得到了迅速的发展。分子的复杂性使它们成为研究的挑战，但也为增强对许多有趣效应的敏感性提供了机会。与双原子分子相比，多原子分子提供了更多的复杂性，但仍“足够简单”以进行激光冷却和控制。尽管激光冷却分子本身仍然是研究前沿，但有许多提议的和正在进行的实验试图将超冷温度实现的高级控制与分子的固有灵敏度相结合。从这个角度出发，我们讨论了一些应用，其中激光冷却的多原子分子可能为基础物理的精密测量提供优势，
