Dynamic generation of spin spirals of moiré trapped carriers via exciton mediated spin interactions
Chengxin Xiao, Yong Wang, Wang Yao
Stacking transition metal dichalcogenides (TMDs) to form moiré superlattices has provided exciting opportunities to explore many-body correlation phenomena of the moiré trapped car…
Highly Anisotropic Excitons and Multiple Phonon Bound States in a Van der Waals Antiferromagnetic Insulator
Kyle Hwangbo, Qi Zhang, Qianni Jiang +9
Two-dimensional semiconducting systems, such as quantum wells and transition metal dichalcogenides, are the foundations to investigate low dimensional light-matter interactions. To…
Nonlinear optics in the electron-hole continuum in 2D semiconductors: two-photon transition, second harmonic generation and valley current injection
Pu Gong, Hongyi Yu, Yong Wang +1
We investigate two-photon transitions to the electron-hole scattering continuum in monolayer transition-metal dichalcogenides, and identify two contributions to this nonlinear opti…
Coulomb effects on topological band inversion in the moiré of WSe/BAs heterobilayer
Qizhong Zhu, Qingjun Tong, Huazheng Sun +2
Quantum spin Hall (QSH) insulator with large gap is highly desirable for potential spintronics application. Here we realize electrically tunable QSH insulator with large gap in van…
Optical selection rules for excitonic Rydberg series in the massive Dirac cones of hexagonal 2D materials
Pu Gong, Hongyi Yu, Yong Wang +1
We investigate the optical transition selection rules for excitonic Rydberg series formed in massive Dirac cones. The entanglement of the exciton envelop function with the pseudosp…
Interlayer coupling in commensurate and incommensurate bilayer structures of transition metal dichalcogenides
Yong Wang, Zhan Wang, Wang Yao +2
The interlayer couplings in commensurate and incommensurate bilayer structures of transition metal dichalcogenides are investigated with perturbative treatment. The interlayer coup…
Topological mosaic in Moiré superlattices of van der Waals heterobilayers
Qingjun Tong, Hongyi Yu, Qizhong Zhu +3
Van der Waals (vdW) heterostructures formed by 2D atomic crystals provide a powerful approach towards designer condensed matter systems. Incommensurate heterobilayers with small tw…
Anomalous light cones and valley optical selection rules of interlayer excitons in twisted heterobilayers
Hongyi Yu, Yong Wang, Qingjun Tong +2
We show that, because of the inevitable twist and lattice mismatch in heterobilayers of transition metal dichalcogenides, interlayer excitons have six-fold degenerate light cones a…
