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 effect in the photonic emission of the system by reordering of the one-photon optical transitions, 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. 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.

量子点-腔系统中奇偶变形引起的谱三重峰的形成

在这项工作中,我们对Lindblad主方程方法中的泵浦耗散QD腔系统的光发射特性进行了研究,其中腔模是通过Heisenberg代数(RDHA)的R变形实现建模的。我们发现,与RDHA相关的奇偶变形参数通过单光子光学跃迁的重排在系统的光子发射中引起了集体效应,并且证明了该参数有两个临界值,其中一个新的在发射光谱中出现光谱三重态的类型。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机制的特征。
