原子物理学之外的冷原子

Cold atoms beyond atomic physics

Lucas Madeira, Vanderlei S. Bagnato

摘要:

在过去的25年里,玻色-爱因斯坦凝聚体(BEC)和简并费米气体的制备和控制取得了很大进展。在这些冷原子系统中捕获、冷却和调整粒子间相互作用的进展导致人们可以对它们施加前所未有的控制。这项工作旨在表明,研究冷原子系统获得的知识可以应用于与它们有相似性和相似性的其他领域,前提是也知道并考虑到差异。我们专注于两个特定的领域,核物理和统计光学。核物理的讨论发生在考虑BCS-BEC交叉,其中我们比较冷费米气体与核和中子物质和原子核。我们将玻色-爱因斯坦凝聚和原子激光联系起来,通过两个系统的物质波性质来与统计光学进行类比。最后,我们提出了一些挑战,如果解决,将增加我们对冷原子系统的理解,从而,相关领域。

英文摘要:

In the last 25 years, much progress has been made producing and controlling Bose-Einstein condensates (BECs) and degenerate Fermi gases. The advances in trapping, cooling and tuning the interparticle interactions in these cold atom systems lead to an unprecedented amount of control that one can exert over them. This work aims to show that knowledge acquired studying cold atom systems can be applied to other fields that share similarities and analogies with them, provided that the differences are also known and taken into account. We focus on two specific fields, nuclear physics and statistical optics. The nuclear physics discussion occurs with the BCS-BEC crossover in mind, in which we compare cold Fermi gases with nuclear and neutron matter and nuclei. We connect BECs and atom lasers through both systems' matter-wave character for the analogy with statistical optics. Finally, we present some challenges that, if solved, would increase our understanding of cold atom systems and, thus, the related areas.
