我们研究了自旋 1 和自旋 2 玻色爱因斯坦凝聚态混合物在零磁场下的基态相。除了自旋内相互作用之外，还引入了两个自旋相关相互作用系数来描述自旋间相互作用。我们系统地探索了广泛的参数空间，并获得了包含丰富种类的相图。例如，存在一个相，其中自旋 1 和自旋 2 向量相对于彼此倾斜，打破了轴对称性。
We investigate the ground-state phases of a mixture of spin-1 and spin-2 Bose-Einstein condensates at zero magnetic field. In addition to the intra-spin interactions, two spin-dependent interaction coefficients are introduced to describe the inter-spin interaction. We systematically explore the wide parameter space, and obtain phase diagrams containing a rich variety of phases. For example, there exists a phase in which the spin-1 and spin-2 vectors are tilted relative to each other breaking the axial symmetry.
