文章介绍了国际上微重力环境下冷原子物理及其应用的研究工作:空间原子钟、原子干涉仪、超冷原子物理和建议中的广义相对论的探索。文中简要介绍了中国科学院上海光学精密机械研究所在微重力环境下所进行的空间原子钟、玻色-爱因斯坦凝聚和原子芯片等研究工作。
We review the field of eold atom physics and its applications in a microgravity environment, including atomic clocks in space, atomic interferometers, ultra-cold atom physics, and the proposed investigation of general relativity. A brief introduction is presented of the research in the Shanghai Institute of Optics and Fine Mechanics on atomic clocks in space, Bose-Einstein condensation and atom chips in a microgravity environment.
