摘要:

冷原子气体已成为探索基础物理的典型系统,同时也为量子技术中的应用提供了可能。该领域的加速发展催生了一套高度先进的工程手段,例如可以调节相互作用、塑造外部几何结构、在具有不同性质的大量原子种类中进行选择,或控制原子数量。特别是,可以在低维条件下操作并将原子系统驱动到强关联区域。在这篇综述中,我们从理论视角讨论了限制在低维中的少体冷原子系统的最新进展。我们主要关注一维玻色系统,并首先介绍其静态性质,然后回顾由关联存在所激发的量子动力学过程的最新研究。除了讨论这些系统中出现的基本物理现象外,我们还概述了常用的计算和数值工具及方法,从而对该领域提供平衡而全面的综述。最后,我们对这些关联系统中值得探索的可能未来方向给出了展望。

英文摘要:

Cold atomic gases have become a paradigmatic system for exploring fundamental physics, which at the same time allows for applications in quantum technologies. The accelerating developments in the field have led to a highly advanced set of engineering techniques that, for example, can tune interactions, shape the external geometry, select among a large set of atomic species with different properties, or control the number of atoms. In particular, it is possible to operate in lower dimensions and drive atomic systems into the strongly correlated regime. In this review, we discuss recent advances in few-body cold atom systems confined in low dimensions from a theoretical viewpoint. We mainly focus on bosonic systems in one dimension and provide an introduction to the static properties before we review the state-of-the-art research into quantum dynamical processes stimulated by the presence of correlations. Besides discussing the fundamental physical phenomena arising in these systems, we also provide an overview of the calculational and numerical tools and methods that are commonly used, thus delivering a balanced and comprehensive overview of the field. We conclude by giving an outlook on possible future directions that are interesting to explore in these correlated systems.
