论文摘要
在这项工作中，我们对Lindblad Master方程方法中的泵送QD-cavity系统的光发射特性进行了研究，其中通过Heisenberg代数（RDHA）对R型实现进行了腔模式。我们发现，与RDHA相关的奇偶元变形参数通过重新排序系统的单光子光学跃迁而产生了集体现象，并且证明该参数有两个关键值，其中在发射光谱中出现了新型的光谱三重态。此外，我们的结果表明，根据变形参数的临界值，在发射光谱中观察到的光谱三重态同时显示出弱耦合和强耦合方案的特征。
In this work, we conduct an investigation on the optical emission properties of a pumped-dissipative QD-cavity system within the Lindblad master equation approach, where the cavity mode is modeled through the R-deformed realization of the Heisenberg algebra (RDHA). We found that the parity deformation parameter associated with the RDHA gives rise to a collective phenomenon by reordering the one-photon optical transitions of the system, and it is demonstrated that there are two critical values for this parameter where a new type of spectral triplet arises in the emission spectrum. Moreover, our results reveal that depending on the critical value of the deformation parameter, the spectral triplets observed in the emission spectrum exhibit signatures of the weak- and strong-coupling regimes simultaneously.
