摘要:

我们提出了一个结合经典和量子电动力学描述的两个圆偏振量子发射器之间的耦合举行以上的金属表面支持表面等离子体。取决于它们的位置和它们的固有频率,发射极-发射极相互作用从互易性发展到非互易性,这使得该系统成为在纳米级手性耦合的高度可调平台。通过放松严格的材料和几何约束的手征,我们探讨了系统中的相干和耗散耦合机制之间的相互作用。因此,我们揭示了一个准手征制度,其中它的量子光学性质是由其subradiant状态,引起非常尖锐的光谱特征和强的光子相关。

英文摘要:

We present a combined classical and quantum electrodynamics description of the coupling between two circularly-polarized quantum emitters held above a metal surface supporting surface plasmons. Depending on their position and their natural frequency, the emitter-emitter interactions evolve from being reciprocal to nonreciprocal, which makes the system a highly tunable platform for chiral coupling at the nanoscale. By relaxing the stringent material and geometrical constraints for chirality, we explore the interplay between coherent and dissipative coupling mechanisms in the system. Thus, we reveal a quasi-chiral regime in which its quantum optical properties are governed by its subradiant state, giving rise to extremely sharp spectral features and strong photon correlations.
