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学领域进行了多年的非正式合作。美国和波兰之间重新建立正式的合作项目使这些合作得以延续和继续。罗切斯特大学的约瑟夫·h·埃伯利（Joseph H. Eberly）和波兰科学院物理研究所的伊沃·比亚利尼基-比鲁拉（Iwo Bialynicki-Birula）之间的合作尤其富有成果，他们专注于研究原子和光子之间的相互作用。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涨落的强相干光束。这个项目将扩大合作，包括实验工作者的参与，特别是匹兹堡大学的J.E. Bayfield和华沙大学的C. Radzewicz。预计该项目将对我们对量子、非线性光学和原子物理学的基本理解作出进一步的重要贡献。该项目实现了美国国家科学基金会美国-东欧合作科学项目的目标，即通过使美国和东欧的顶尖专家在共同感兴趣和有能力的领域结合互补的人才和汇集资源，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.
