光谱无序下动态调制Tavis-Cumming模型的超辐射

Superradiance in dynamically modulated Tavis-Cumming model with spectral disorder

Alexander D. White, Rahul Trivedi, Kalyan Narayanan, Jelena Vučković

摘要:

超辐射是来自共同耦合到相同光学模式的量子发射器的光子的增强发射。然而,量子发射器的共振频率的无序会干扰这种效应。本文研究了动态调制的Tavis-Cummings模型中超辐射与光谱无序的相互作用。通过数值模拟和分析计算,我们表明,有效的协同性的超辐射模式,它总是形成在大量的发射器,可以成倍地增强与量子控制协议调制的谐振频率的光学模式。我们的研究结果是相关的实验演示超辐射效应在固态量子光学系统,其中的光谱紊乱是一个重要的技术障碍,实现光子介导的发射极-发射极耦合。

英文摘要:

Superradiance is the enhanced emission of photons from quantum emitters collectively coupling to the same optical mode. However, disorder in the resonant frequencies of the quantum emitters can perturb this effect. In this paper, we study the interplay between superradiance and spectral disorder in a dynamically modulated Tavis-Cummings model. Through numerical simulations and analytical calculations, we show that the effective cooperativity of the superradiant mode, which is always formed over an extensive number of emitters, can be multiplicatively enhanced with a quantum control protocol modulating the resonant frequency of the optical mode. Our results are relevant to experimental demonstration of superradiant effects in solid-state quantum optical systems, wherein the spectral disorder is a significant technological impediment towards achieving photon-mediated emitter-emitter couplings.
