论文摘要
腔积聚的过渡金属二甲基化型激子最近已成为研究强烈的轻度相互作用和相关腔量子电动力学现象的有前途的平台。尽管这种激子腔系统通常被建模为耦合的谐波振荡器，以说明富固态环境，但需要纳入激子 - phonon相互作用的效果。我们通过在激子相互作用中包括现象学变形潜力来对系统进行建模，并阐明了激发型光致发光与相对于激子共振的红色腔模式的实验测量的优先耦合。此外，我们预测并通过实验证实了这种优先耦合的温度依赖性。通过准确捕获激子 - phonon相互作用，我们的模型阐明了腔体综合过渡金属二进制基因源的潜力，以开发低功率的经典和量子技术。
Cavity-integrated transition metal dichalcogenide excitons have recently emerged as a promising platform to study strong light-matter interactions and related cavity quantum electrodynamics phenomena. While this exciton-cavity system is typically modeled as coupled harmonic oscillators, to account for the rich solid-state environment the effect of exciton-phonon interaction needs to be incorporated. We model the system by including a phenomenological deformation potential for exciton-phonon interactions and we elucidate the experimentally measured preferential coupling of the excitonic photoluminescence to the cavity modes red-detuned with respect to the exciton resonance. Furthermore, we predict and experimentally confirm the temperature dependence of this preferential coupling. By accurately capturing the exciton-phonon interaction, our model illuminates the potential of cavity-integrated transition metal dichalcogenides for development of low-power classical and quantum technologies.
