论文摘要
我们证明，自旋轨道耦合态是在中性磁性自旋颗粒中产生的，穿过电场。轨道角动量的量化轴平行于电场，因此可以创建纵向和横向轨道角动量。此外，我们表明粒子的总角动量是保守的。最后，我们提出了一个中子光学实验来测量横向效应。
We demonstrate that spin-orbit coupled states are generated in neutral magnetic spin 1/2 particles travelling through an electric field. The quantization axis of the orbital angular momentum is parallel to the electric field, hence both longitudinal and transverse orbital angular momentum can be created. Furthermore we show that the total angular momentum of the particle is conserved. Finally we propose a neutron optical experiment to measure the transverse effect.
