This proposal describes a theoretical study of important problems in the many bodyphysics of cold atoms and related systems. Building on previous work, the investigatorwill explore several topical subjects, including (1) properties of a Fermi gas near aFeshbach resonance; (2) spectra of atomic hydrogen on Helium surfaces andembedded in a molecular hydrogen matrix; and (3)dynamics of tuning the interactionstrength for atoms trapped in a strong optical lattice. These projects are motivated by (i)interest in fundamental physical properties of cold atoms, (ii) desires to use cold atomsas a model system to understand other many body systems, and (iii) puzzles found inongoing experiments. Studying cold atoms has impact on many body problems incondensed matter and nuclear physics.

该提案描述了对冷原子和相关系统的许多物理物理学中的重要问题的理论研究。在之前的工作基础上，研究人员将探索几个主题，包括（1）费什巴赫共振附近费米气体的特性； (2) 氦表面上和嵌入氢分子基质中的原子氢光谱； (3)调节强光学晶格中原子相互作用强度的动力学。这些项目的动机是（i）对冷原子基本物理特性的兴趣，（ii）希望使用冷原子作为模型系统来理解其他许多身体系统，以及（iii）在正在进行的实验中发现的难题。研究冷原子对凝聚态物质和核物理等许多身体问题都有影响。
