U.S.-Poland Cooperative Research on Photophysics of Atoms and Electrons

美国和波兰的物理学家在量子光学和原子物理领域进行了几年的非正式合作。美国和波兰之间重新建立正式的合作计划，使其有可能恢复和继续这些合作。罗切斯特大学的Joseph H.Eberly和波兰科学院物理研究所的Iwo Bialyicki-Birula之间的合作特别富有成果，重点是研究相互作用的原子和光子。在其他成就中，美国和波兰团队的成员负责首次观察到双光子电离中多光子跃迁的统计增强，以及携带大规模量子波动的强相干光束。该项目将扩大合作范围，包括实验工作者的参与，特别是匹兹堡大学的J.E.贝菲尔德和华沙大学的C.Radzewicz。预计这个项目将对我们对量子和非线性光学以及原子物理的基本理解做出进一步的重要贡献。该项目实现了NSF美国-东欧合作科学计划的目标，即通过使美国和东欧的顶尖专家能够将互补的人才结合在一起，并在相互之间具有很强互补性和竞争力的领域汇集资源，从而促进科学知识的发展。

U.S. and Polish physicists have collaborated informally for several years in the areas of quantum optics and atomic physics. The re-establishment of formal programs for cooperation between the United States and Poland makes it possible to renew and continue these collaborations. The partnership between Joseph H. Eberly of the University of Rochester and Iwo Bialynicki-Birula of the Instsitute of Physics ofthe Polish Academy of Sciences has been particular fruitful, focusing on the study of atoms and photons in interaction with each other. Among other achievements, members of the U.S. and Polish teams have been responsible for the first observations of the statistical enhancement of multiphoton transitions in two-photon ionization, and of intense coherent light beams carrying large-scale quantum flucations. This project will extend the collaboration to include the involvement of experimental workers, particularly J.E. Bayfield of the University of Pittsburgh and C. Radzewicz of Warsaw University. It is expected that this project will result in futher important contributions to our fundamental understanding of quantum and nonlinear optics and atomic physics. The project fulfills the NSF U.S.-Eastern Europe Cooperative Science Program's objective of advancing scientific knowledge by enabling leading experts in the United States and Eastern Europe to combine complementary talents and pool resources in areas of strong mutual interset and competence.
