弱相互作用的稀原子玻色-爱因斯坦凝聚体（BECs）已被证明是宏观尺度上非线性动力学和量子效应研究的一个有吸引力的背景。最近，弱相互作用，稀原子BECs已被用于研究量子湍流实验和理论，主要是由这些量子气体中可用的高度控制刺激。在本文中，我们鼓励使用弱相互作用的稀原子bec来研究湍流，讨论了湍流的特征机制，并简要回顾了一些量子湍流的研究和最近的结果。我们将重点讨论湍流的三个阶段——湍流的产生、稳定状态和衰减——并强调一些关于我们对每个阶段的理解的基本问题。
Weakly interacting, dilute atomic Bose-Einstein condensates (BECs) have proved to be an attractive context for the study of nonlinear dynamics and quantum effects at the macroscopic scale. Recently, weakly interacting, dilute atomic BECs have been used to investigate quantum turbulence both experimentally and theoretically, stimulated largely by the high degree of control which is available within these quantum gases. In this article we motivate the use of weakly interacting, dilute atomic BECs for the study of turbulence, discuss the characteristic regimes of turbulence which are accessible, and briefly review some selected investigations of quantum turbulence and recent results. We focus on three stages of turbulence – the generation of turbulence, its steady state and its decay – and highlight some fundamental questions regarding our understanding in each of these regimes.
