Every-other-layer Dipolar Excitons in a Spin-Valley locked Superlattice
Yinong Zhang, Chengxin Xiao, Dmitry Ovchinnikov +7
Monolayer semiconducting transition metal dichalcogenides possess broken inversion symmetry and strong spin-orbit coupling, which leads to unique spin-valley locking effect. In 2H…
Time-Reversal Even Charge Hall Effect from Twisted Interface Coupling
Dawei Zhai, Cong Chen, Cong Xiao +1
Under time-reversal symmetry, a linear charge Hall response is usually deemed to be forbidden by the Onsager relation. In this work, we discover a scenario for realizing a time-rev…
Intercell Moiré Exciton Complexes in Electron Lattices
Xi Wang, Xiaowei Zhang, Jiayi Zhu +12
Excitons, Coulomb-bound electron-hole pairs, play a fundamental role in both optical excitation and correlated phenomena in solids. When an exciton interacts with other quasi-parti…
Light-Induced Ferromagnetism in Moiré Superlattices
Xi Wang, Chengxin Xiao, Heonjoon Park +9
Many-body interactions between carriers lie at the heart of correlated physics. The ability to tune such interactions would open the possibility to access and control complex elect…
