标题： Cavity optomagnonics with spin-orbit coupled photons

摘要： 我们实验实现了腔光磁子系统，其中铁磁材料的球体支持光子的驻波模式（WGMs）和磁子的静磁模式。 我们观察到由磁子诱导的布里渊散射产生的边带信号中明显的非互易性和不对称性。 WGM光子的自旋-轨道耦合特性、其几何双折射以及磁子动力学中的时间反演对称性破缺在散射过程中施加了角动量选择规则，并解释了观察到的现象。 该系统的独特特性可能在量子光学和自旋电子学的交叉领域找到有趣的应用。 显示英文摘要

摘要： We experimentally implement a system of cavity optomagnonics, where a sphere of ferromagnetic material supports whispering gallery modes (WGMs) for photons and the magnetostatic mode for magnons. We observe pronounced nonreciprocity and asymmetry in the sideband signals generated by the magnon-induced Brillouin scattering of light. The spin-orbit coupled nature of the WGM photons, their geometric birefringence and the time-reversal symmetry breaking in the magnon dynamics impose the angular-momentum selection rules in the scattering process and account for the observed phenomena. The unique features of the system may find interesting applications at the crossroad between quantum optics and spintronics.
