Robust AC Quantum Spin Hall Effect without Participation of Edge States
W. Y. Deng, H. Geng, Wei Luo +4
The quantum spin Hall (QSH) effect in the DC regime, which has been intensively researched, relies on the existence of symmetry-protected edge states. Here, we demonstrate that a Q…
Pressure-Induced Confined Metal from the Mott Insulator Sr3Ir2O7
Yang Ding, Liuxiang Yang, Cheng-Chien Chen +12
The spin-orbit Mott insulator Sr3Ir2O7 provides a fascinating playground to explore insulator-metal transition driven by intertwined charge, spin, and lattice degrees of freedom. H…
Topological Spin and Valley Pumping in Silicene
Wei Luo, L. Sheng, B. G. Wang +1
We propose an experimental scheme to realize adiabatic topological spin and valley pumping by using silicene subject to an in-plane electric field with amplitude and a…
Non-adiabatic topological spin pumping
W. Y. Deng, W. Luo, H. Geng +3
Based on the Floquet scattering theory, we analytically investigate the topological spin pumping for an exactly solvable model. Floquet spin Chern numbers are introduced to charact…
