论文摘要
从理论上讲，我们基于改进的Devreese-Huybrechts-Lemmens模型，研究金属卤化物钙钛矿（MHP）中Angulon的光学吸收，其中准粒子angulon状态的形成起源于MHP的无机八个笼子中旋转的有机阳离子。我们发现，当入射光子的能量与Angulon的量子水平匹配时，出现共振光吸收峰。此外，吸收强度取决于声子角动量的量子状态。这些理论结果提供了重要的见识，以研究浸入多体环境中的旋转分子的角动量的重新分布。
We theoretically study the optical absorption of an angulon in the metal halide perovskites (MHP) based on the improved Devreese-Huybrechts-Lemmens model, where the formation of quasiparticle angulon states originates from the organic cation rotating in the inorganic octahedral cage of MHP. We find that the resonance optical absorption peaks are appeared when the energy of incident photon matches the quantum levels of angulon. Moreover, the intensity of absorption depends on the quantum states of phonon angular momentum. These theoretical results provide significant insight to study the redistribution of angular momenta for the rotational molecules immersed into the many-body environment.
