Catalog of Altermagnetism in Magnetic Wallpaper/Space Groups and Nonsymmorphic Altermagnets
Congcong Le, Fan Cui, Iao-Fai Io +3
Conventional altermagnetism, characterized by compensated collinear spin alignment and spin splitting, exhibits identical spin states at opposite momenta. In this work, we employ a…

Classification of High-Ordered Topological Nodes towards Moiré Flat Bands in Twisted Bilayers
Fan Cui, Congcong Le, Qiang Zhang +3
At magic twisted angles, Dirac cones in twisted bilayer graphene (TBG) can evolve into flat bands, serving as a critical playground for the study of strongly correlated physics. Wh…
