This work will exploit recent advances in atomic de Broglie wave interferometry for precise measurements of rotation and for new tests of the Equivalence Principle. The potential impact of Bose-Einstein condensed sources on future precision measurements will be experimentally assessed through application of atomic AC Josephson effects to sensitive and precise measurements of acceleration and h/m (the ratio of Planck's constant to atomic mass), and through the study of squeezed many-body atomic states in the context of achieving statistical sensitivities below the atom shot-noise limit. The dynamic evolution of entangled many-body quantum states will be studied in connection with this latter goal.

这项工作将利用原子德布罗意波干涉术的最新进展，用于精确测量旋转和对等价原理进行新的测试。玻色-爱因斯坦凝聚源对未来精密测量的潜在影响将通过将原子AC约瑟夫森效应应用于敏感而精确的加速度和h/m(普朗克常数与原子质量之比)的测量，以及通过在低于原子散粒噪声限制的统计灵敏度的背景下研究压缩多体原子态来实验评估。我们将结合后一个目标来研究纠缠多体量子态的动态演化。
