在相互作用的冷原子云中出现的密度波动显示了早期宇宙演化的特征方面。[另见Hung等人的报告]乍一看，冷原子和宇宙学有着天壤之别；它们在能量、长度和时间上的物理尺度都截然不同。在本期第1213页，Hung等人。(1)超冷量子简并气体时间演化中声振荡的观测报告。这表明，类似的基本物理原理支配着它们非平衡演化的各个方面。
The emergence of density fluctuations in a cloud of interacting cold atoms shows characteristic aspects of the evolution of the early universe. [Also see Report by Hung et al.] At first sight, cold atoms and cosmology could not be more different; they are characterized by vastly different physical scales in energy, length, and time. On page 1213 of this issue, Hung et al. (1) report on the observation of acoustic oscillations in the time evolution of an ultracold quantum degenerate gas. This suggests that similar fundamental physics principles govern aspects of their nonequilibrium evolution.
