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…
Double and Quadruple Flat Bands tuned by Alternative magnetic Fluxes in Twisted Bilayer Graphene
Congcong Le, Qiang Zhang, Cui Fan +2
Twisted bilayer graphene (TBG) can host the moiré energy flat bands with two-fold degeneracy serving as a fruitful playground for strong correlations and topological phases. Howeve…
Ni-based transition-metal trichalcogenide monolayer: a strongly correlated quadruple-layer graphene
Yuhao Gu, Qiang Zhang, Congcong Le +3
We investigate the electronic physics of layered Ni-based trichalcogenide NiPX (X=S, Se), a member of transition-metal trichalcogenides (TMTs) with the chemical formula, ABX$_3…
Electronic Physics and Possible Superconductivity in Layered Orthorhombic Cobalt Oxychalcogenides
Congcong le, Shengshan Qin, Jiangping Hu
We suggest that Cobalt-Oxychalcogenide layers constructed by vertex sharing CoAO (A=S,Se,Te) tetrahedra, such as BaCoAO, are strongly correlated multi-orbital electron syst…
Topological phase in non-centrosymmetric material NaSnBi
Xia Dai, Congcong Le, Xianxin Wu +3
We predict that a non-centrosymmetric material NaSnBi locates in a three-dimensional non-trivial topological phase under ambient pressure based on first-principle calculations. By…
