论文摘要
我们研究了微波型型宏伟的宏伟机械系统中强探针场的吸收和传播特性。该杂种系统由两种铁磁材料YTTrium Iron Garnet（YIG）组成，该球形与单个空腔模式强烈耦合。除了由于强烈的光子 - 磁通相互作用而产生的两个镁诱导的透明度（MIT）外，由于存在非线性声子 - 磁子相互作用，我们还观察到宏伟的透明度（MMIT）。此外，我们讨论了系统中多个FANO共振的出现和可调性。我们发现，由于强烈的光子 - 马格诺耦合，探针场的组延迟可以显着增强。溢流或悬体的传播取决于镁的频率，这可以通过外部偏置磁场轻松调节。此外，也可以使用控制场功率控制传输场的组延迟。
We investigate the absorption and transmission properties of a weak probe field under the influence of a strong control field in a hybrid cavity magnomechanical system in the microwave regime. This hybrid system consists of two ferromagnetic material yttrium iron garnet (YIG) spheres strongly coupled to a single cavity mode. In addition to two magnon-induced transparency (MIT) that arise due to strong photon-magnon interactions, we observe a magnomechanically induced transparency (MMIT) due to the presence of nonlinear phonon-magnon interaction. In addition, we discuss the emergence and tunability of the multiple Fano resonances in our system. We find that due to strong photon-magnon coupling the group delay of the probe field can be enhanced significantly. The subluminal or superluminal propagation depends on the frequency of the magnons, which can be easily tuned by an external bias magnetic field. Besides, the group delay of the transmitted field can also be controlled with the control field power.
