微重力下的玻色-爱因斯坦凝聚体和重力的基本试验

Bose-Einstein condensates in microgravity and fundamental tests of gravity

Christian Ufrecht, Albert Roura, Wolfgang P. Schleich

摘要:

光脉冲原子干涉仪对惯性和引力效应高度敏感。因此,它们是检验引力物理的有希望的候选者。本文综述了重力基础实验的现状和建议。它们包括引力常量$G$的测量、弱等效原理的检验、暗能量的直接搜索和引力波的探测。特别强调的是在微重力环境下的长时间干涉测量,伴随着灵敏度的大幅增加。此外,还讨论了玻色-爱因斯坦凝聚体作为原子源的优缺点。

英文摘要:

Light-pulse atom interferometers are highly sensitive to inertial and gravitational effects. As such they are promising candidates for tests of gravitational physics. In this article the state-of-the-art and proposals for fundamental tests of gravity are reviewed. They include the measurement of the gravitational constant $G$, tests of the weak equivalence principle, direct searches of dark energy and gravitational-wave detection. Particular emphasis is put on long-time interferometry in microgravity environments accompanied by an enormous increase of sensitivity. In addition, advantages as well as disadvantages of Bose-Einstein condensates as atom sources are discussed.
