人们对在低于1 K的温度下产生冷分子和在低于1 mK的温度下产生超冷分子非常感兴趣。这些分子在从精密测量到量子信息存储和处理等领域具有潜在的应用，并且超冷极性分子的量子气体有望表现出新的量子相。此外，冷分子为碰撞物理学开辟了一个新的领域，主要是长程力和散射共振。最近在从室温冷却分子和在超冷原子气体中形成分子方面都取得了重大进展。随着这些技术的成熟，以及更容易获得冷和超冷样品，将有可能在以前无法获得的能量下进行碰撞研究。这篇聚焦文章将突出一些背景和动机，研究碰撞在低能量，并将引导读者到最近的文章，最近的实验进展。
There is great interest in the production of cold molecules, at temperatures below 1 K, and ultracold molecules, at temperatures below 1 mK. Such molecules have potential applications in areas ranging from precision measurement to quantum information storage and processing, and quantum gases of ultracold polar molecules are expected to exhibit novel quantum phases. In addition, cold molecules open up a new domain for collision physics, dominated by long-range forces and scattering resonances. There have been major recent advances both in cooling molecules from room temperature and in forming molecules in ultracold atomic gases. As these techniques mature, and cold and ultracold samples are more accessible, collision studies at previously unavailable energies will be possible. This spotlight article will highlight some of the background and motivation for studying collisions at low energies and will direct readers to recent articles on the recent experimental advancements.
