由于能够控制原子相互作用强度、物种数量、密度和几何形状，由工程磁势或光学势限制的超冷原子是研究在固态下难以实现或探测的现象的理想选择。在这里，我们回顾原子气体中的量子输运现象，镜像，可以更好地阐明或显示在介观和纳米系统中观察到的根本差异。我们讨论了原子气体中的传输实验的重大进展，冷原子和凝聚态系统中的传输之间的相似性和差异，并调查了难以在常规设置中验证的理论预测。
Ultracold atoms confined by engineered magnetic or optical potentials are ideal to study phenomena otherwise difficult to realize or probe in the solid state, thanks to the ability to control the atomic interaction strength, number of species, density and geometry. Here, we review quantum transport phenomena in atomic gases that mirror and can either better elucidate or show fundamental differences with respect to those observed in mesoscopic and nanoscopic systems. We discuss the significant progress in transport experiments in atomic gases, the similarities and differences between transport in cold atoms and in condensed matter systems, and survey theoretical predictions that are difficult to verify in conventional set-ups.
