Berry curvature memory through electrically driven stacking transitions
Jun Xiao, Ying Wang, Hua Wang +9
In two-dimensional layered quantum materials, the stacking order of the layers determines both the crystalline symmetry and electronic properties such as the Berry curvature, topol…

Electron-hole Hybridization in Bilayer Graphene
Siqi Wang, Xianqing Lin, Mervin Zhao +8
Band structure determines the motion of electrons in a solid, giving rise to exotic phenomena when properly engineered. Drawing an analogy between electrons and photons, artificial…

Magnetically-defined topological edge plasmons in edgeless electron gas
Dafei Jin, Yang Xia, Thomas Christensen +11
Topological materials bear gapped excitations in bulk yet protected gapless excitations at boundaries. Magnetoplasmons (MPs), as high-frequency density excitations of two-dimension…
