论文摘要
具有微重力的太空中的超冷原子实验可以实现稀有原子 - 玻色 - 内施泰因冷凝物(BEC),具有宏观占用较大的职业数量,并且凝聚态寿命长大,这可以通过在许多振荡周期内校准形状振荡频率进行精确的测量。在本文中,我们建议通过具有形状振荡的超冷原子BEC测量牛顿重力常数,尽管它在实验上具有挑战性。我们还对约束修改后的牛顿电位(例如幂律电位,Yukawa相互作用和脂肪吸引力)进行初步观点。 $(1-100)\,\ mathrm {nhz} $的频率测量的分辨率最多最多适合职业数量$ 10^9 $,仅超过实验可以实现的数字$ n \ sim10^6-10^8 $,是可行的,可以限制经过改进的牛顿潜能,而Yukawa Interaction Extractive则超过了当前的超越当前的互动限制。
Ultra-cold atom experiment in space with microgravity allows for realization of dilute atomic-gas Bose-Einstein condensate (BEC) with macroscopically large occupation number and significantly long condensate lifetime, which allows for a precise measurement on the shape oscillation frequency by calibrating itself over numerous oscillation periods. In this paper, we propose to measure the Newtonian gravitational constant via ultra-cold atom BEC with shape oscillation, although it is experimentally challenging. We also make a preliminary perspective on constraining the modified Newtonian potential such as the power-law potential, Yukawa interaction, and fat graviton. A resolution of frequency measurement of $(1-100)\,\mathrm{nHz}$ at most for the occupation number $10^9$, just one order above experimentally achievable number $N\sim10^6-10^8$, is feasible to constrain the modified Newtonian potential with Yukawa interaction greatly beyond the current exclusion limits.
