Linear exciton Hall and Nernst effects in monolayer two-dimensional semiconductors
Weilong Guo, Lianguo Li, Qingjun Tong +1
This paper focuses on the study of linear exciton Hall and Nernst effects in monolayer two-dimensional (2D) semiconductors, employing the semi-classical transport theory. By derivi…
Förster valley-orbit coupling and topological lattice of hybrid moiré excitons
Huiyuan Zheng, Ci Li, Hongyi Yu +1
Hybrid exciton in moiré superlattices of two-dimensional (2D) semiconductors inherits the electric dipole, strong moiré trapping, and stacking optical selection rules from its in…
Topological classification and edge states of magnons in honeycomb ferromagnets
Youwen wang, Qiutong Wang, Qingjun Tong +1
We study the topological classification and related edge states of magnons in ferromagnets on honeycomb that can be described by a class of single-particle bosonic Bogoliubov-de Ge…
Non-Hermitian theory of valley excitons in two-dimensional semiconductors
Qiutong Wang, Ci Li, Qingjun Tong
Electron-hole exchange interaction in two-dimensional transition metal dichalcogenides is extremely strong due to the dimension reduction, which promises valley-superposed excitoni…
