Observation of a Mott quantum spin Hall insulator in twisted WSe2
Yifei Jin, Yaqi Ma, Aoqian Zhang +9
Quantum spin Hall (QSH) insulators and Mott insulators are conventionally regarded as distinct insulating phases, arising from band topology and strong Coulomb interactions, respec…

All-optical magnetic imaging with spin defects in van der Waals materials at Angstrom-scale
Ning Wang, Jianming Cai, Chao Lei
Magnetic imaging with ultra-high spatial resolution is crucial to exploring the magnetic textures of emerging quantum materials. We propose a novel magnetic imaging protocol that a…
