The rotating excitons in two-dimensional materials: Valley Zeeman effect and chirality

Autor: Cui, Yu, Ma, Xin-Jun, Deng, Jia-Pei, Li, Shao-Juan, Yang, Ran-Bo, Li, Zhi-Qing, Wang, Zi-Wu

We propose the rotational dynamics of the intralayer and interlayer excitons with their inherent momenta of inertia in the monolayer and bilayer transition metal dichalcogenides, respectively, where the new chirality of exciton is endowed by the rota

Theory of all-coupling angulon for molecules rotating in many-body environment

Autor: Liu, Yi-Yan, Cui, Yu, Zhang, Xiao-Zhe, Yang, Ran-Bo, Li, Zhi-Qing, Wang, Zi-Wu

The formation of angulon, stemming from the rotor (molecule or impurity) rotating in the quantum many-body field, adds a new member in the quasiparticle's family and has aroused intensively interests in multiple research fields. However, the analysis

Mobile defects as mediated states for charge-carrier trapping in metal halide perovskites quantum dots

Autor: Liu, Xiao-Yi, Li, Wei-Ping, Cui, Yu, Li, Shao-Juan, Yang, Ran-Bo, Li, Zhi-Qing, Wang, Zi-Wu

The migration motion of defects in metal halide perovskites quantum dots (MHPQDs) results in charge-carrier trapping become more complicated. We study two-step trapping mediated by mobile defects between the ground state of MHPQDs and a fixed-depth d

Microscopic theory of Raman scattering for the rotational organic cation in metal halide perovskites

Autor: Cui, Yu, Liu, Yi-Yan, Deng, Jia-Pei, Zhang, Xiao-Zhe, Yang, Ran-Bo, Li, Zhi-Qing, Wang, Zi-Wu

A gap exists in microscopic understanding the dynamic properties of the rotational organic cation (ROC) in the inorganic framework of the metal halide perovskites (MHP) to date. Herein, we develop a microscopic theory of Raman scattering for the ROC
