摘要:

光磁学和光机学具有从可调谐光源到量子信息科学的光学操纵的各种应用。在这里,我们提出了一个声子和磁振子相互作用的混合系统,该系统可以通过基于辐射压力和磁光效应的电磁场进行调谐。研究了磁振子和声子在电磁场作用下的自能以及热噪声的影响。此外,借助于例外点的动力学包围,给出了混合系统的拓扑特征,并发现了这些包围下的手征特征。

英文摘要:

Optomagnonics and optomechanics have various applications ranging from tunable light sources to optical manipulation for quantum information science. Here, we propose a hybrid system with the interaction between phonon and magnon which could be tuned by the electromagnetic field based on the radiation pressure and magneto-optical effect. The self energy of the magnon and phonon induced by the electromagnetic field and the influence of the thermal noise are studied. Moreover, the topological features of the hybrid system is illustrated with resort to the dynamical encircling with the exceptional points, and the chiral characteristics under these encirclements are found.
