项目摘要

0129020GallagherThis three-year award for U.S.-France collaboration in atomic, molecular and optical physics involves Thomas Gallager, Pierre Pillet and graduate students at the University of Virginia and the Laboratoire Aime Cotton in Orsay, France respectively. The goal is to use cold Rydberg gases as a controllable test system for several different kinds of experiments. Cold Rydberg atoms mimic an amorphous solid, the properties of which can be manipulated using small tuning electric fields or by changing the Rydberg state. This cooperative research program will explore collectively this phenomena in cold Rydberg atom samples, the Rydberg to plasma evolution, and dipole-dipole interactions in frozen Rydberg gases. The main questions addressed are: How does ultracold plasma containing cold atoms in a well-defined Rydberg state come to equilibrium? What key role do dipole-dipole interactions play in quantum logic gates? The French group brings to this collaboration expertise in high-resolution laser spectroscopy and cold atom manipulation. This is complemented by US expertise in manipulation of Rydberg atoms. This award represents the US side of joint proposals to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the US investigator and graduate students. CNRS will support the visits of the French researchers and graduate students to the United States. The collaboration will advance fundamental understanding of the atomic-solid state connection in cold Rydberg gases and this phenomena's applications in plasma and condensed matter physics.

这个为期三年的美法原子、分子和光学物理合作奖项分别授予Thomas Gallager、Pierre Pillet和法国奥赛大学Aime Cotton实验室的研究生。目标是使用冷里德堡气体作为一种可控的测试系统，用于几种不同类型的实验。冷里德堡原子模拟无定形固体，其性质可以通过使用小的可调电场或通过改变里德堡状态来操纵。这项合作研究计划将集体探索冷里德堡原子样品中的这种现象，里德堡到等离子体的演化，以及冷冻里德堡气体中的偶极-偶极相互作用。主要讨论的问题是：含有冷原子的超冷等离子体如何在明确定义的里德堡态中达到平衡？偶极-偶极相互作用在量子逻辑门中扮演着什么关键角色？这家法国集团将高分辨率激光光谱学和冷原子操纵方面的专业知识带到了这次合作中。此外，美国在操纵里德堡原子方面的专业知识也起到了补充作用。该奖项代表美方向NSF和法国国家科学研究中心(CNRS)提出的联合建议。NSF将支付这名美国调查员和研究生的旅费和生活费。CNRS将支持法国研究人员和研究生访问美国。这项合作将促进对冷里德堡气体中原子-固态联系的基本理解，以及这一现象在等离子体和凝聚态物理中的应用。
