Study of Boundary Effect in Superfluid Helium-3

我们进行了实验，以阐明超流3He在自由面和边界发生的反常现象。特别是，我们使用表面上的电子或表面下的离子作为探针。在我们的研究结果中，观察到了一个相当意想不到的效果。也就是说，在超流3He-A相中，在平行于表面的电场的驱动下，离子受到垂直于驱动电场和表面法线方向的力。这是超流体H^3e-A手性的直接证据。

We carried out experiment to elucidate anomalous phenomena in superfluid 3He occurring at free surfaces and boundaries. In particular, we employ, electrons on the surface or ions below the surface as a probe. Among our research findings, quite an unexpected effect was observed. That is, in superfluid 3He-A phase, ions driven parallel to the surface by an electric field experienced force which is in the direction perpendicular to both the driving electric field and surface normal. This is a direct evidence for a chiral property of superfluid H^^3e-A.
