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…

Unconventional ferroelectricity in half-filling states of antiparallel stacking of twisted WSe2
Liheng An, Zishu Zhou, Xuemeng Feng +9
Abstract: We report on emergence of an abnormal electronic polarization in twisted double bilayer WSe2 in antiparallel interface stacking geometry, where local centrosymmetry of at…
