U.S.-France Cooperative Research: Collective and Co- operative Effects in a Frozen Rydberg Gas

这项为期三年的奖项将支持弗吉尼亚大学的Thomas Gallagher和法国奥赛的Aime Cotton实验室的Pierre Pillet在原子、分子和光学物理方面的美法合作研究项目的继续。他们研究的目的是调查激光冷却及其在相对密集的冷里德堡原子样本碰撞研究中的应用。他们将研究远红外超辐射脉泽和多体碰撞能量转移。拟议的实验将在激光冷却光束和磁光陷阱中使用碱原子进行。这位美国研究人员将他在里德堡原子碰撞方面的专业知识带到了这次合作中。法国研究人员在激光冷却技术和超辐射方面的专业知识补充了这一点。该项目将促进我们对里德堡原子在光散射和集体光发射过程中的影响的理解。这可能最终会影响到半导体激光器的制造。

This three-year award will support the continuation of a U.S.-France cooperative research project in atomic, molecular and optical physics between Thomas Gallagher of the University of Virginia and Pierre Pillet of the Aime Cotton Laboratory in Orsay, France. The objective of their research is to investigate laser cooling and its application to collisional studies of relatively dense samples of cold Rydberg atoms. They will study far infrared superadiant masers and multibody collisional energy transfer. The proposed experiments will be done with alkali atoms in laser cooled beams and in magneto-optical traps. The U.S. investigator brings to this collaboration his expertise on collisions of Rydberg atoms. This is complemented by the French investigator's expertise in laser cooling techniques and superadiance. The project will advance our understanding of the effects of Rydberg atoms in light scattering and collective light emission processes. This may eventually impact on the fabrication of diode lasers.
