- 摘要:
- 为了研究非厄米混合系统中的快慢光传播性质,提出了一个非厄米磁量子电动力学(QED)混合模型.该模型由2个微波腔和1个钇铁石榴石组成.模型采用强泵浦场驱动磁子,采用弱探测场探测微波腔.研究表明:通过调节腔与磁子之间的相互作用强度和微波腔与磁子的耗散比,可以增加磁子诱导放大效应和提高快慢光的传播速度.该研究结果可为量子光学操纵、量子信息存储以及灵敏光开关的研究提供参考.
- Abstract:
- In order to study the propagation characteristics of fast and slow light in non - Hermitian hybrid systems, a non - Hermitian magnetic quantum electrodynamics(QED)hybrid model is proposed.The model consists of two microwave cavities and one yttrium iron garnet(YIG).The model uses a strong pump field to drive the magnon and a weak detection field to detect the microwave cavity.The research shows that the magnon - induced amplification and the propagation speed of fast and slow light can be increased by adjusting the action strength of cavities and magnets as well as the dissipation ratio in the microwave cavity and the magnon.The results can provide a reference for the research of quantum optical manipulation, quantum information storage and sensitive optical switch.
