Theoretical Atomic, Molecular, and Optical Physics at JILA

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该小组项目旨在深入研究一系列广泛的问题，这些问题源于对超冷原子和分子气体的全面了解，以及如何操纵这些气体来设计感兴趣的系统。特别感兴趣的是碱土原子和类似的原子（如镱），以及极性物质。这些原子在各种应用中提供了丰富的未开发的潜力，如光学频率标准，不寻常的凝聚态系统建模和量子信息设备。这项工作将加深对两体、三体和四体相互作用的理论理解，这些相互作用对冷气体的制备、稳定和控制至关重要。互补的工作将集中在利用这些属性，以产生一套详细的操作说明建模，否则棘手的凝聚态哈密顿量，否则描述新的运输possibilities.The更广泛的影响，计划的工作产生的一部分，从有利的前景，大大增加了凝聚态系统的理解。通过在光学晶格上原子气体的高度可控环境中设计模拟，该小组可能能够为高温超导体，巨磁阻材料等材料提供基本见解。此外，该项目将影响研究生的培训，他们将能够与JILA的不同理论和实验研究小组进行互动。研究人员将继续为社区外展计划做出贡献，如公开讲座和无障碍物理文章，组织研讨会，并保持对物理界的服务。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This group project aims to delve into a broad range of problems stemming from the desire to understand gases of ultracold atoms and molecules in full detail, and how to manipulate these gases to engineer systems of interest. Of particular interest will be the alkaline-earth atoms and similar atoms (such as ytterbium), and polar species. These atoms offer a wealth of untapped potential in applications as diverse as optical frequency standards, modeling of unusual condensed matter systems, and quantum information devices. The work will deepen theoretical understanding of two, three, and four-body interactions that are essential to the preparation, stability, and control of cold gases. Complementary work will focus on exploiting these properties to generate a detailed set of how-to instructions for modeling otherwise intractable condensed matter Hamiltonians, or else to describe novel transport possibilities.The broader impact of the planned work arises in part from the favorable prospects for adding significantly to the body of understanding of condensed matter systems. By designing simulations in the highly-controllable environment of an atom gas on an optical lattice, the group may be able to provide fundamental insights into such materials as high-temperature superconductors, colossal magnetoresistance materials, and many others. In addition, the project will impact the training of graduate students, who will be able to interact with the different theoretical and experimental research groups at JILA. The investigators will continue to contribute to community outreach programs such as public lectures and accessible physics articles, to organize workshops, and to maintain service to the physics community.
