Floquet-engineered Valley Topology with Anisotropic Response in 1T'-WSe and Janus WSeTe monolayers
Zhe Li, Haijun Cao, Lijuan Li +3
Valley topology has emerged as a key concept for realizing new classes of quantum states. Here, we investigate Floquet-engineered topological phase transitions in anisotropic 1T'-W…
Light-engineered Multichannel Quantum Anomalous Hall Effect in High-order Topological Plumbene
Zhe Li, Fangyang Zhan, Haijun Cao +3
Floquet engineering severs as a forceful technique for uncovering high Chern numbers of quantum anomalous Hall (QAH) states with feasible tunability in high-order topologically ins…
Laser-engineered -point Topology in Trigonal Bismuthene
Zhe Li, Haijun Cao, Sheng Meng
The -point topology represents a significant segment in the family of topological insulators. Here we provide a comprehensive prediction of light-induced -point-based topolog…
Highly tunable band structure in ferroelectric R-stacked bilayer WSe
Zhe Li, Prokhor Thor, George Kourmoulakis +6
Transition metal dichalcogenide homobilayers unite two frontiers of quantum materials research: sliding ferroelectricity, arising from rhombohedral (R) stacking, and moiré quantum…
