Observation of fourfold Dirac nodal line semimetal and its unconventional surface responses in sonic crystals
Chang-Yin Ji, Xiao-Ping Li, Zheng Tang +5
Three-dimensional nodal line semimetals (NLSMs) provide remarkable importance for both enrich topological physics and wave management. However, NLSMs realized in acoustic systems a…
Optical bulk-boundary dichotomy in a quantum spin Hall insulator
Junfeng Han, Pengcheng Mao, Hailong Chen +17
The bulk-boundary correspondence is a key concept in topological quantum materials. For instance, a quantum spin Hall insulator features a bulk insulating gap with gapless helical…
Layer sliding and twisting induced electronic transitions in correlated magnetic 1T-NbSe2 bilayers
Jiaqi Dai, Jingsi Qiao, Cong Wang +9
Correlated two-dimensional (2D) layers, like 1T-phases of TaS2, TaSe2 and NbSe2, exhibit rich tunability through varying interlayer couplings, which promotes the understanding of e…
Recent advances of defect-induced spin and valley polarized states in graphene
