Comprehensive Study of Cold and Ultracold Collisions

该项目将集中于量子相干控制、激光物质相互作用、锥形相交、Efimov物理和双分子反应动力学的精确数值结果的生成。重点将放在绘制阈值行为，圆锥交叉和量子共振的影响。光子系统的相互作用将为研究和控制化学反应提供丰富的环境，特别是在超冷和低温下。控制化学反应将对许多研究领域产生长期影响。控制哪些化学物质的形成可能会导致新化合物的产生，并降低生产某些产品的成本。强激光场的应用包括碰撞诱导吸收和激光诱导碰撞能量转移。这些项目涉及最先进的理论和数值方法，用于研究和控制各种有和没有激光场的原子-硅藻碰撞。正在使用几种不同的方法，以便研究人员自己以及科学界可以看到每种方法的相对优点和缺点。该项目将资助两名优秀的研究生。该集团致力于为学生提供最好的教育，通过在夏季提供丰富的教育机会，通过在原子，分子，光学和化学物理方面的高级研讨会。该项目将增加来自代表性不足地区的学生在科学和工程方面的机会，同时加强俄克拉荷马州的科学和技术。该项目将鼓励教师和学生参与俄克拉荷马大学K20中心的全州教育推广活动。

This project will concentrate on the generation of accurate numerical results of quantum coherent-control, laser-matter interactions, conical intersections, Efimov physics, and bimolecular reaction dynamics. Concentration will be on maping out threshold behavior, influences of conical intersections and quantum resonances. The photon-system interactions will provide a rich environment for studying and controlling chemical reactions especially at ultracold and cold temperatures. Controlling chemical reactions will have long term consequences for many research fields. Controlling which chemical species are formed may lead to the production of new compounds as well as reducing the costs of producing certain products. Applications of intense laser fields include collision induced absorption and laser induced collisional energy transfer. The projects involve state-of-the-art theories and numerical methods for studying and controlling a variety of atom-diatom collisions with and without laser fields. Several different approaches are being used so that the researchers themselves, as well as the scientific community, can see relative advantages and disadvantages of each method.The project will support two excellent graduate students. The group is committed to providing the best possible education for its students, by providing enriched educational opportunities through advanced seminars in atomic, molecular, optical, and chemical physics during the summer. This project will increase the opportunities of students from under-represented regions in science and engineering while enhancing Oklahoma science and technology. This project will encourage faculty and students to participate in the statewide educational outreach activities of the K20 Center at the University of Oklahoma.
