A nonreciprocal optomagnonic device that has dual properties of classical and quantum nonreciprocity is proposed by Hong‐Yu Liu, Rong‐Can Yang, and co‐workers in article number 2000196. The system consists of a magnon mode and a mechanical mode of the YIG sphere and a spinning microwave oscillator. Due to the Fizeau light‐dragging effect, the effective cavity frequency can be shifted by the direction of the input light, leading to a nonreciprocal magnon–phonon entangled state.

光电子设备：旋转微波磁机械系统中的不可逆传输和不可逆纠缠（物理9/2020号）

刘洪宇，杨荣灿和他的同事在文章编号2000196中提出了一种具有经典和量子不可逆性双重性质的不可逆光子磁共振设备。该系统由YIG球的磁振模式和机械模式组成和旋转的微波振荡器。由于Fizeau的光拖曳效应，有效腔频率可以通过输入光的方向移动，从而导致不可逆的磁振子-声子纠缠态。
