A scheme is presented to realize nonreciprocal photon blockade by exploiting a spinning optomechanical resonator, where the photon blockade effect appears when the spinning resonator is driven from one side but vanishes from the other side. This quantum nonreciprocity originates from the Sagnac effect and Kerr-type interaction between photons in the spinning resonator. We analyze the dynamics of the system in the weak driving regime, and discuss the photon statistical properties by calculating the second-order correlation function. Based on master-equation simulations, we also study numerical results of the steady state of the system and the validity of the analytical solution, and find that it is feasible to achieve nonreciprocal photon blockade by choosing appropriate parameters in a spinning optomechanical resonator.

提出了一种利用旋转光机械谐振器实现非互易光子阻挡的方案，其中当旋转谐振器从一侧驱动但从另一侧消失时，光子阻挡效应出现。这种量子非互易性源于自旋谐振器中光子之间的萨格纳克效应和克尔型相互作用。我们分析系统在弱驱动状态下的动力学，并通过计算二阶相关函数讨论光子统计特性。基于主方程模拟，我们还研究了系统稳态的数值结果和解析解的有效性，发现通过在旋转光机械谐振器中选择适当的参数来实现非互易光子阻挡是可行的。
