具有非零自旋的气态玻色-爱因斯坦凝聚具有反映内部自由度的多分量序参量。它们表现出丰富多样的超流和磁现象，与超流氦-3相似或互补。原子气体前所未有的可操作性使得旋量凝聚成为探索对称性破缺、拓扑激发以及超流性和磁性之间相互作用的独特场所。本文概述了这些主题。
Gaseous Bose-Einstein condensates with nonzero spin feature multicomponent order parameters that reflect the internal degrees of freedom. They exhibit a rich variety of superfluid and magnetic phenomena similar or complementary to those of superfluid helium-3. The unprecedented degree of manipulability of atomic gases makes spinor condensates a unique playground for exploring symmetry breaking, topological excitations, and the interplay between superfluidity and magnetism. An overview of these subjects is provided.
