论文摘要
使用易于平面磁铁和电荷中的拓扑缺陷之间的映射，我们研究涡度和自旋电流之间的相互作用。我们证明了涡度的流动伴随着横向自旋电流的一代 - 这种效应可以称为涡度的自旋大厅效应。我们研究了整个BKT转变的这种效果，并确定了耗散和自旋不保存在从自旋超流体到扩散自旋转运的跨界中的作用。我们的结果为依靠涡度和自旋流量的低功率计算设备铺平了道路。
Using mapping between topological defects in an easy-plane magnet and electrical charges, we study interplay between vorticity and spin currents. We demonstrate that the flow of vorticity is accompanied by the transverse spin current generation -- an effect which can be termed as the spin Hall effect of vorticity. We study this effect across the BKT transition and establish the role of dissipation and spin non-conservation in the crossover from spin superfluidity to diffusive spin transport. Our results pave the way for low power computing devices relying on vorticity and spin flows.
