- 摘要:
- 为了研究腔磁力系统中的吸收和透射光谱,建立了一个混合双腔磁力系统.该系统由两个相互正交的微波腔和1个放置在中心的铁磁材料(钇铁石榴石球,YIG)组成.研究显示:通过调节各子系统间的相互作用强度和腔1与磁子的耗散比可以增强系统中的磁子诱导透明(MIT)现象和磁力诱导透明(MMIT)现象,并可实现快慢光的便捷调控; 通过调节系统中的相互作用强度和非共振参数可获得更好的法诺共振效果.该研究结果可为研究量子现象、量子信息储存和高精度量子传感测量等提供良好参考.
- Abstract:
- In order to study the absorption and transmission spectrum in a cavity magnomechanical system, a hybrid two - cavity magnomechanical system was established.The system consists of two microwave cavities orthogonal to each other and a ferromagnetic material(yttrium iron garnet sphere, YIG), placed in the center.The study demonstrates that the magnon - induced transparency(MIT)and magnomechanical - induced transparency(MMIT)phenomena in the system can be enhanced by adjusting the interaction strengths among individual subsystems and the dissipation ratio between cavity 1 and magnon, and convenient manipulation of fast - slow light propagation can be realized.Better Fano resonance effects can be obtained by adjusting the system interaction strengths and non - resonant parameters.These results can provide a valuable reference for studying quantum phenomena, quantum information storage and high - precision quantum sensing measurement.
