论文摘要
我们表明，在半导体设备中制造的几何耦合偏振子凝结物是能够模拟具有给定特征的分子的多功能系统。特别是，我们考虑了极化二聚体，三聚体和四二聚体和四二聚体中的振荡和固定对称性和不对称状态，以及它们在真实和傅立叶空间中的发光度。振荡状态的光谱重量与离散光谱线有关。它们的数量和分离可以通过更改冷凝物的数量和几何形状来控制，这反映了耦合强度。我们还表明，不对称固定状态在一个系统中结合了离散和连续的自由度。连续的自由度由阶段表示，而离散的自由度则由密度不对称给出。我们的工作为设计可控制的人工分子的方式铺平了道路，并按需制造了一系列特性。
We show that geometrically coupled polariton condensates fabricated in semiconductor devices are versatile systems capable of simulating molecules with given characteristics. In particular, we consider oscillatory and stationary symmetric and asymmetric states in polariton dimers, trimers, and tetrads and their luminosity in real and Fourier space. The spectral weights of oscillatory states are associated with discrete spectral lines. Their number and separation can be controlled by changing the number and geometry of condensates, reflected by the coupling strengths. We also show that asymmetric stationary states combine discrete and continuous degrees of freedom in one system. The continuous degree of freedom is represented by the phase while the discrete degree of freedom is given by density asymmetry. Our work paves the way to engineer controllable artificial molecules with a range of properties manufactured on demand.
