Atoms that interact strongly at low energy exhibit universal behavior that does not depend on details of atomic physics. The development of methods for trapping atoms, cooling them to ultralow temperatures, and manipulating their interaction strengths has made universality of practical importance for controlling atoms and molecules. The ultimate goal of this project is to predict the behavior of few-body and many-body systems consisting of strongly-interacting ultracold atoms and the weakly-bound molecules formed by these atoms. Although this project is focussed primarily on ultracold atoms, universality ensures that the results will also be applicable to other fields of science, including nuclear physics, high energy physics, condensed matter physics, and astrophysics.This award will be used primarily to support a graduate student who will be working on this research project. The training received by the graduate student in carrying out the research will contribute to the building of a diverse scientific workforce. The mix of analytical and numerical computation required by this project is excellent preparation for both academic and industrial research.

在低能量下强烈相互作用的原子表现出不依赖于原子物理学细节的普遍行为。 捕获原子、将它们冷却到超低温以及操纵它们的相互作用强度的方法的发展使得控制原子和分子的普遍性具有实际重要性。 该项目的最终目标是预测由强相互作用的超冷原子和由这些原子形成的弱束缚分子组成的少体和多体系统的行为。 虽然该项目主要集中在超冷原子上，但其普遍性确保了其成果也将适用于其他科学领域，包括核物理，高能物理，凝聚态物理和天体物理。该奖项将主要用于支持将从事该研究项目的研究生。 研究生在开展研究方面接受的培训将有助于建设一支多样化的科学队伍。该项目所需的分析和数值计算的混合是学术和工业研究的良好准备。
