玻色-爱因斯坦凝聚的相变是不寻常的，因为它不一定是由粒子间的相互作用驱动的，但可以发生在理想气体中，作为激发态的纯统计饱和的结果。然而，相互作用是任何系统达到热平衡所必需的，因此需要在有限时间内发生冷凝。在这一章中，我们回顾了相互作用在玻色-爱因斯坦凝聚中的作用，包括理论和实验。我们专注于谐波捕获的超冷原子气体进行测量，但也讨论了如何将这些结果与均匀系统的情况下，这是更多的理论研究，也更相关的其他实验系统。
The phase transition to a Bose-Einstein condensate is unusual in that it is not necessarily driven by inter-particle interactions but can occur in an ideal gas as a result of a purely statistical saturation of excited states. However, interactions are necessary for any system to reach thermal equilibrium and so are required for condensation to occur in finite time. In this chapter we review the role of interactions in Bose-Einstein condensation, covering both theory and experiment. We focus on measurements performed on harmonically trapped ultracold atomic gases, but also discuss how these results relate to the uniform-system case, which is more theoretically studied and also more relevant for other experimental systems.
