论文摘要
预计在二维材料中缺陷的光 - 物质相互作用将受到与声子的强耦合的深刻影响。在这项工作中，我们结合了HBN缺陷的A量从头算计算，并完全量子机械和数值精确的描述腔缺失系统，以阐明这种影响。我们表明，即使在弱的光结合耦合下，空腔缺失系统的动力演化也具有明确的非马克维亚声子效应的特征，并且线性吸收光谱显示出在强光 - 偶联方案中杂交光 - 谱状态的出现。我们强调我们的方法是一般的，可以应用于多种材料/缺陷系统。
Light-matter interactions of defects in two dimensional materials are expected to be profoundly impacted by strong coupling to phonons. In this work, we combine ab initio calculations of a defect in hBN, with a fully quantum mechanical and numerically exact description of a cavity-defect system to elucidate this impact. We show that even at weak light-matter coupling, the dynamical evolution of the cavity-defect system has clear signatures of non-markovian phonon effects, and that linear absorption spectra show the emergence of hybridised light-matter-phonon states in regimes of strong light-matter coupling. We emphasise that our methodology is general, and can be applied to a wide variety of material/defect systems.
