摘要

现有的天基冷原子实验已经证明了微重力在改善观测时间和最小化自由演化的相干物质波的膨胀能量和速率方面的效用。在本文中，我们探索了空间实验的潜力，不仅利用微重力，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，来扩展超冷原子的极限。讨论了这种诱人的可能性，即有一天这样的实验可能能够探测质量接近普朗克质量的量子物体的物理学。

Exploring the limits of ultracold atoms in space

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 Planck mass is discussed.

期刊介绍： Driven by advances in technology and experimental capability, the last decade has seen the emergence of quantum technology: a new praxis for controlling the quantum world. It is now possible to engineer complex, multi-component systems that merge the once distinct fields of quantum optics and condensed matter physics. Quantum Science and Technology is a new multidisciplinary, electronic-only journal, devoted to publishing research of the highest quality and impact covering theoretical and experimental advances in the fundamental science and application of all quantum-enabled technologies.
