玻色-爱因斯坦凝聚（BE）是一种宏观数量的粒子占据单粒子态的现象。一旦系统经历BE凝聚，相当一部分粒子就会步调一致，导致许多壮观的宏观量子现象。这篇文章描绘了BE凝聚的基本方面，强调自旋自由度。在这里，规范和自旋自由度耦合起来，产生了丰富的旋量超流性和拓扑激发。
Bose-Einstein (BE) condensation is a phenomenon in which a macroscopic number of particles occupy a single-particle state. Once a system undergoes BE condensation, a significant fraction of particles behave in lockstep, leading to a number of spectacular macroscopic quantum phenomena. This article delineates fundamental aspects of BE condensates with an emphasis on spin degrees of freedom. Here the gauge and spin degrees of freedom are coupled to produce a rich variety of spinor superfluidity and topological excitations.
