论文摘要
由于波函数的非平凡动量分布，涡旋状态效率的极化具有丰富的结构。这种更大的自由提供了一个独特的机会，可以在异国情调的两极分化状态下准备费米，这对于飞机波式的fermions不存在。基于所谓的自旋轨道状态，在理论上还是在实验上研究了一个奇特的涡流兆，其极化表现出$ z_n $对称性并研究其衰变。我们研究发射电子的方位角分布，发现它表现出与初始状态相同的对称性（$ z_n $）。
Polarization of a vortex state fermion has rich structure due to the nontrivial momentum distribution of wave function. This larger freedom provides an unique opportunity to prepare fermions in exotic polarized states, which do not exist for plane-wave state fermions. Based on the so called spin-orbit state which was studied both theoretically and experimentally, we put forward a peculiar vortex muon whose polarization exhibits $Z_n$ symmetry and study its decay. We investigate the azimuthal distribution of the emitted electrons and find that it exhibits the same symmetry ($Z_n$) as the initial state.
