US-France Cooperative Research: Theoretical and ExperimentalStudies of the Interaction of Radiation with Matter

该奖项将支持纽约大学物理系的Paul Berman博士与奥赛的Aime Cotton实验室和巴黎的Hertzienne del‘Ecole Normer Superieure实验室的两组法国科学家之间的合作研究。这项研究的目的是加深我们对辐射与物质相互作用的理解。在这个联合项目中，将进行理论和实验研究，以考察原子系综对两个或更多辐射场的响应。研究的重点将是原子响应对外场的相干性质和原子蒸气中发生的碰撞过程的敏感性。该研究计划的具体目标是：(1)强随机场与原子相互作用的实验和理论研究；(2)以非线性谱线形状出现的各种碰撞诱导共振结构的统一解释；(3)观察到碰撞诱导共振的新情况的理论和实验研究；以及(4)辐射与物质的多波相互作用的完全量子化理论。这项工作将汇集三个在原子和光学物理的理论和实验研究方面具有重要专业知识的机构。

This award will support collaborative research between Dr. Paul Berman, Department of Physics, New York University and two groups of French scientists at the Laboratoire Aime Cotton, Orsay and the Laboratoire de Spectroscopie Hertzienne del'Ecole Normale Superieure, Paris. The objective of this research is to further our understanding of the interaction of radiation with matter. In this joint project, both theoretical and experimental studies will be undertaken to examine the response of an ensemble of atoms to two or more radiation fields. Research will focus on the sensitivity of the atomic response to the coherence properties of the applied fields and to collisional processes occurring in the atomic vapor. Specific goals of the research program are: (1) a experimental and theoretical study of the interaction of intense stochastic fields with atoms; (2) a unified approach to explain various collision-induced resonant structures that appear in nonlinear spectroscopic line shapes; (3) a theoretical and experimental study of new situations in which collision-induced resonances are observed; and (4) a fully-quantized theory of multiple-wave interactions of radiation with matter. This work will bring together three institutions with significant expertise in the theoretical and experimental studies of atomic and optical physics.
