论文摘要
由于各种重要的应用，混合量子状态的水平分裂发生的两个子系统之间的强耦合（由量子发射器和光子模式发生）一直是量子物理和纳米光子学的中心主题。光子发射或吸收的光谱狂犬分裂已被实验表征在相等性假设下与水平分裂相同的强耦合。在这里，我们第一次揭示了平等假设是无效的。正是无效的导致强耦合的相对性和多样性，其特征在于光谱狂犬分裂到测量的子系统上，这与它们的耗散性衰减高度相关。从较大的衰减的子系统可以更容易地观察到强的耦合，并且可以分类为伪，黑暗，中，超强的相互作用制度。我们还建议对这些新型预测的未来实验观察的耦合等离子体激子系统的原型。我们的工作为纳米结构的光结合互动带来了新的基本见解，这将刺激该领域的进一步研究。
The strong coupling between two subsystems consisting of quantum emitters and photonic modes, at which the level splitting of mixed quantum states occurs, has been a central subject of quantum physics and nanophotonics due to various important applications. The spectral Rabi-splitting of photon emission or absorption has been adopted to experimentally characterize the strong coupling under the equality assumption that it is identical to the level splitting. Here, we for the first time reveal that the equality assumption is not valid. It is the invalidity that results in the relativity and diversity of the strong coupling characterized by the spectral Rabi-splitting to the measured subsystems, highly correlated with their dissipative decays. The strong coupling is easier to be observed from the subsystem with larger decay, and can be classified into pseudo-, dark-, middle-, and super-strong interaction regimes. We also suggest a prototype of coupled plasmon-exciton system for possibly future experiment observations on these novel predictions. Our work brings new fundamental insight to the light-matter interaction in nanostructures, which will stimulate further researches in this field.
