我们首次观测到了超流体He-3的极性相。这一相出现在He-3中，限制在一种新型气凝胶中，具有几乎平行的链排列，起到有序杂质的作用。我们的实验与理论预测定性地一致，并表明在其他具有非传统库珀配对的系统中(例如，在非传统超导体中)，在存在各向异性杂质的情况下也可以发现类似的现象。
We report the first observation of the polar phase of superfluid He-3. This phase appears in He-3 confined in a new type of aerogel with a nearly parallel arrangement of strands which play the role of ordered impurities. Our experiments qualitatively agree with theoretical predictions and suggest that in other systems with unconventional Cooper pairing (e.g., in unconventional superconductors) similar phenomena may be found in the presence of anisotropic impurities.
