手征超流体中的几何诱导

Geometric Induction in Chiral Superfluids

Qing-Dong Jiang, A. Balatsky

摘要:

我们探讨了覆盖在曲面上的手征超流薄膜的性质。由于序参量的矢量性质,几何规范场出现,并导致了一些可观察到的效应,如反常涡旋几何相互作用和曲率诱导的质量/自旋超流。我们将我们的理论应用到几个著名的手征超流体$\rm ^3 He$的阶段,并获得实验观察到的签名。我们进一步讨论了柔性几何形状的情况下,软表面可以适应自己,以补偿手征超流体的应变。几何结构和手征超流序之间的相互作用提供了一个迷人的途径来控制和操纵量子态与应变。

英文摘要:

We explore the properties of chiral superfluid thin films coating a curved surface. Due to the vector nature of the order parameter, a geometric gauge field emerges and leads to a number of observable effects such as anomalous vortex-geometric interaction and curvature-induced mass/spin supercurrents. We apply our theory to several well-known phases of chiral superfluid $\rm ^3 He$ and derive experimentally observable signatures. We further discuss the cases of flexible geometries where a soft surface can adapt itself to compensate for the strain from the chiral superfluid. The proposed interplay between geometry and chiral superfluid order provides a fascinating avenue to control and manipulate quantum states with strain.
