摘要:

现有的空基冷原子实验已证明微重力可用于改进观测时间,并可用于尽量减少自由演化的相干物质波的膨胀能量和速率。在本文中,我们探讨了空间实验的潜力,以扩大超冷原子的限制,不仅利用微重力,而且还利用空间环境的其他方面,如非常好的真空和极冷的温度。诱人的可能性,这样的实验可能有一天能够探测物理的量子物体的质量接近普朗克质量进行了讨论。

英文摘要:

Existing space-based cold atom experiments have demonstrated the utility of microgravity for improvements in observation times and for minimizing the expansion energy and rate of a freely evolving coherent matter wave. In this paper we explore the potential for space-based experiments to extend the limits of ultracold atoms utilizing not just microgravity, but also other aspects of the space environment such as exceptionally good vacuums and extremely cold temperatures. The tantalizing possibility that such experiments may one day be able to probe physics of quantum objects with masses approaching the Plank mass is discussed.
