与通常的自旋-轨道相互作用（SOI）引起的单体自旋霍尔效应（SHE）不同，我们提出了由粒子间偶极-偶极相互作用（DDI）引起的多体自旋霍尔效应，并在超冷磁性原子系统中进行了演示.虽然SOI通常需要打破空间反演对称性，DDI保留了它。多体SHE原则上可以在大偶极矩的广泛系统中观察到，并提供了一个强大的工具来产生自旋电流，自旋电子学和原子电子学的重要组成部分。
In contrast to the ordinary spin Hall effect (SHE), which is a single-body phenomenon caused by the spin-orbit interaction (SOI), we propose a many-body SHE induced by the dipole-dipole interaction (DDI) between particles and demonstrate it in a system of ultracold magnetic atoms. While the SOI usually requires the breaking of space-inversion symmetry, the DDI preserves it. The many-body SHE can, in principle, be observed in a wide range of systems with large dipole moments and offers a powerful tool to generate spin currents, an essential ingredient in spintronics and atomtronics.
