论文摘要
我们研究了涉及镁 - 光子和镁 - phonon相互作用的平均时间（PT）对称样型磁机械系统中的镁阻滞效应。在断裂和不间断的PT对称区域中，我们在分析和数值上分别计算了二阶相关函数，并进一步确定了引导的最佳值。通过调整不同的系统参数，我们研究了不同的阻滞机制，并发现在弱参数机制下可以观察到完美的镁阻滞效应。我们的工作铺平了一种实现实验中镁封锁的方法。
We investigate the magnon blockade effect in a parity-time (PT) symmetric-like three-mode cavity magnomechanical system involving the magnon-photon and magnon-phonon interactions. In the broken and unbroken PT-symmetric regions, we respectively calculate the second-order correlation function analytically and numerically and further determine the optimal value of detuning. By adjusting different system parameters, we study the different blockade mechanisms and find that the perfect magnon blockade effect can be observed under the weak parameter mechanism. Our work paves a way to achieve the magnon blockade in experiment.
