U.S.-Japan Joint Seminar: Quantum Electronic Manipulation of Atoms and Fields/September 1990/Kyoto, Japan

这一奖项将支持六名美国科学家参加美日联合研讨会，该研讨会的主题是原子和电磁场的量子电子操纵。这一领域的研究正在产生根本性的新见解和新的应用可能性。目前的努力包括通过激光冷却和捕获来操纵原子和离子；通过激光稳频和产生所谓的“压缩”态来操纵场；以及通过应用腔量子电动力学原理来控制辐射原子过程。这种新获得的产生与正常状态非常不同的光和物质的“非传统”状态的能力，正在为量子力学带来根本的新见解，并在高分辨率光谱、精确频率标准和重力波探测等领域产生潜在的应用。这是因为这些技术提供的可能性，例如，在减少激光的幅度噪声和频率噪声，并在原子光谱学研究中显著减少多普勒效应，导致更准确的原子能级测定和频率和时间的精确测量。研讨会将讨论的具体议题包括(1)囚禁、冷却离子的物理和应用；(2)中性原子的激光冷却和囚禁；(3)激光的超高精度控制；(4)非传统光态的产生；(5)腔量子电动力学。与会者将包括许多在这一系列相互关联的主题领域最活跃的美国和日本研究人员。研讨会将于1990年9月3日至7日在日本京都举行。共同组织者是日本国家标准与技术研究所原子、分子和光学物理中心的William D.Phillips博士和日本东京大学工程学院的Fujio Shimizu博士。此前美日在激光光谱学、量子光学和量子电子学方面的相关研讨会有助于两国相关研究机构了解彼此的最新进展，并促进合作项目和科学家的交流。这次研讨会预计也会有同样的效果。

This award will support the participation of six U.S. scientists in a joint U.S.-Japan seminar on the subject of quantum electronic manipulation of atoms and electromagnetic fields. Research in this area is producing both fundamental new insights and new possibilities for applications. Current efforts include the manipulation of atoms and ions through laser cooling and trapping; the manipulation of fields through laser frequency stabilization and by the production of so- called "squeezed" states; and the control of radiative atomic processes through application of principles of cavity quantum electrodynamics. This newly acquired ability to produce "unconventional" states of light and matter that are very different from their normal states is bringing fundamental new insights into quantum mechanics, as well as giving rise to potential applications in such areas as high resolution spectroscopy, precise frequency standards, and gravity wave detection efforts. This comes about because of the possibilities these techniques offer, for example, in reducing both amplitude noise and frequency noise in laser light, and in significantly reducing Doppler effects in atomic spectroscopic studies, leading to more accurate determinations of atomic energy levels and precise measurements of frequencies and time. Specific topics to be discussed at the seminar include (1) physics and applications of trapped, cooled ions; (2) laser cooling and trapping of neutral atoms; (3) ultrahigh precision control of lasers; (4) generation of unconventional states of light; and (5) cavity quantum electrodynamics. Participants will include many of the U.S. and Japanese researchers most active in this set of strongly interrelated topical areas. The seminar will be held September 3-7, 1990, in Kyoto, Japan. Co-organizers are Dr. William D. Phillips, Center for Atomic, Molecular, and Optical Physics, National Institute of Standards and Technology; and Dr. Fujio Shimizu, Faculty of Engineering, University of Tokyo, Japan. Previous related U.S.-Japan seminars in laser spectroscopy, quantum optics, and quantum electronics served to keep the relevant research communities in the two countries abreast of each other's current progress, and to stimulate collaborative projects and exchanges of scientists. This seminar is expected to be similarly effective.
