The dynamics of arbitrary-order quantum correlations in a cavity magnon-polariton system are investigated based on the quantum master equation in the coherent state representation. The phenomena of Rabi-like oscillation and level repulsion of the average cavity-photon number agree remarkably well with existing experimental observations. The competing nature of coherent and incoherent components in these two cases is further revealed by the second-order quantum coherence of the cavity photons and magnons, which can be systematically tuned by the driving microwave and thermal bath. Our results demonstrate the rich higher-order quantum dynamics induced by magnetic light-matter interaction and serve as an indispensable step toward exploring nonclassical states for cavity photons and magnons in quantum cavity magnonics.

腔磁振子极化系统中的驱动耗散量子动力学

基于相干态表示中的量子主方程，研究了腔磁振子极化系统中任意阶量子关联的动力学。平均腔光子数的类拉比振荡和能级排斥现象与现有的实验观察非常吻合。腔光子和磁振子的二阶量子相干性进一步揭示了这两种情况下相干和非相干分量的竞争性质，可以通过驱动微波和热浴系统地调谐。我们的结果证明了由磁光-物质相互作用引起的丰富的高阶量子动力学，并且是探索量子腔磁子学中腔光子和磁子的非经典状态不可或缺的一步。
