几十年来,理解相干的宏观玻色-爱因斯坦凝聚(BEC)如何从热玻色气体的冷却中出现的问题吸引了大量的理论和实验兴趣。1995年,BEC在弱相互作用稀原子气体中取得了开创性的成就,随后又进行了一些实验研究,研究BEC数的增长及其相干性的发展。最近有兴趣在连接这样的实验的非平衡相变的普遍方面,在静态和动态的临界指数。在这里,自发形成的拓扑结构,如涡旋和孤子在淬火冷原子实验已经使验证的Kibble-Zurek机制预测连续相变中的拓扑缺陷的密度,首先提出的背景下,早期宇宙的演化。本章回顾了BEC形成的理解进展,并讨论了量子气体相变动力学的开放问题和未来的研究方向。
The problem of understanding how a coherent, macroscopic Bose-Einstein condensate (BEC) emerges from the cooling of a thermal Bose gas has attracted significant theoretical and experimental interest over several decades. The pioneering achievement of BEC in weakly-interacting dilute atomic gases in 1995 was followed by a number of experimental studies examining the growth of the BEC number, as well as the development of its coherence. More recently there has been interest in connecting such experiments to universal aspects of nonequilibrium phase transitions, in terms of both static and dynamical critical exponents. Here, the spontaneous formation of topological structures such as vortices and solitons in quenched cold-atom experiments has enabled the verification of the Kibble-Zurek mechanism predicting the density of topological defects in continuous phase transitions, first proposed in the context of the evolution of the early universe. This chapter reviews progress in the understanding of BEC formation, and discusses open questions and future research directions in the dynamics of phase transitions in quantum gases.
