摘要

讨论了镝费米气体在磁偶极-偶极相互作用下获得超流体相的可能性。指出了障碍和可能的解决办法。所需相类似于3He中的A1相和极性β相。预计在镝中，相的宏观性质将由对相互作用的对称性决定。假设观察了具有不同轨道角动量投影的两个能量简并相的形成动力学和自发选择动力学。

Prospects for anisotropic superfluidity in a Fermi gas of dysprosium

The possibility of obtaining superfluid phases for a Fermi gas of dysprosium with a magnetic dipole – dipole interaction is discussed. The obstacles and possible solutions are shown. The required phases are similar to the A1 phase and the polar β phase in 3He. It is expected that in dysprosium, the macroscopic properties of the phase will be determined by the symmetry of the pair interactions. It is assumed to observe the kinetics of phase formation and spontaneous choice between two energy-degenerate phases with different projections of the orbital angular momentum.
