论文摘要
我们在实验上实现了由小磁球加载的圆环的微波腔中的圆形极化的单向腔磁化器。在特殊位置，顺时针和逆时针模式是圆形极化的，因此只有一对伴侣与磁铁伴侣，这破坏了模式退化。我们通过观察和建模微波散射矩阵的非晶状体来揭示光谱能和角动量流的手性质。
We experimentally realize circularly polarised unidirectional cavity magnon polaritons in a torus-shaped microwave cavity loaded by a small magnetic sphere. At special positions the clockwise and counterclockwise modes are circularly polarized, such that only one of them couples to the magnet, which breaks the mode degeneracy. We reveal the chiral nature of the spectral energy and angular momentum flow by observing and modelling non-reciprocities of the microwave scattering matrix.
