Direct Visualization of Room-temperature Stair-stepped Quantum Spin Hall States in Bi4Br4
Zhiqiang Hu, Yuqi Zhang, Yuyang Wang +7
Topological insulators host exotic quantum phenomena such as the quantum spin Hall (QSH) effect, which enables dissipationless one-dimensional edge conduction. Realizing such state…
Terahertz nonlinear response in cuprate superconductors and the Higgs field in doped Mott insulators
Xiang Li, Zheng-Yu Weng
A puzzling phenomenon has been recently revealed in terahertz nonlinear optical response experiments: A third harmonic generation (THG) signal, identified only in the superconducti…
Flat bands and distinct density wave orders in correlated Kagome superconductor CsCrSb
Shuting Peng, Yulei Han, Yongkai Li +15
