我们发展了一种多体方法来研究激子束缚态和周围电子空穴等离子体中导电子带边的行为,重点研究了氧化亚铜中里德伯激子的吸收光谱。带边和激子能级的相互作用进行了数值分析,从而自洽的解决方案相比,半经典德拜近似。我们的研究结果提供了标准,允许验证或排除不同的带边模型对未来的实验数据。
We develop a many-body approach to the behavior of exciton bound states and the conduction electron band edge in a surrounding electron-hole plasma with a focus on the absorption spectrum of Rydberg excitons in cuprous oxide. The interplay of band edge and exciton levels is analyzed numerically, whereby the self-consistent solution is compared to the semiclassical Debye approximation. Our results provide criteria which allow to verify or rule out the different band edge models against future experimental data.
