U.S-France Cooperative Research: Atom-Interferometer based Gyroscope Improvements for Space and Ground-based Tests of General Relativity

这项为期三年的美法合作奖包括耶鲁大学的马克·a·卡塞维奇和他的团队，以及奥赛光学研究所查尔斯·法布里实验室的菲利普·布耶尔和他的团队。合作的目的是开发原子干涉旋转传感器的技术和应用。具体而言，合作涉及：美国热原子束陀螺仪与CNRS原子发现陀螺仪的比较研究；开发了一个使用原子干涉仪陀螺仪测试广义相对论的地基项目；美国宇航局/欧洲航天局依靠原子干涉仪陀螺仪的飞行实验；以及在原子干涉测量中使用玻色-爱因斯坦凝聚原子源。美国和法国集团为此次合作带来了互补的专业知识和可比较的高质量和精密仪器。该奖项代表了美国方面向美国国家科学基金会和法国国家科学研究中心（CNRS）提出的联合提案。美国国家科学基金会将支付美国研究人员和研究生的旅费和生活费。法国科学研究中心将支持法国研究人员访问美国。这项合作将促进对物质波动性质的基本理解，以及在太空飞行和导航中使用原子干涉仪陀螺仪。

0004059KasevichThis three-year award for U.S.-France collaboration involves Mark A. Kasevich and his group at Yale University and Philippe Bouyer and his group at the Laboratoire Charles Fabry de l'Institut d'Optique in Orsay. The aim of the collaboration is the development of techniques and applications of atom interferometric rotation sensors. In particular, the collaboration addresses: comparison studies of US thermal atomic beam gyroscope with CNRS atomic found gyroscope; development of a ground-based program to test General Relativity using atom interferometer gyroscopes; NASA/European Space Agency flight experiments relying on atom interferometer gyroscopes; and uses of Bose-Einstein condensed atomic sources for atom interferometry. The US and French groups bring to this collaboration complementary expertise and comparable, high quality and precision instruments. This award represents the US side of a joint proposal to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the US investigator and graduate students. CNRS will support the visits of the French researchers to the United States. The collaboration will advance fundamental understanding of the wave nature of matter as well as the use of atom interferometer gyroscopes in space flights and navigation.
