Modulation of charge density waves in a twisted vortex moire superlattice
Qian Fang, Yanhao Shi, Jingyi Duan +11
Twisted moire superlattices in van-der-Waals heterostructures provide a powerful platform for engineering correlated states through moire-band reconstruction. However, whether glob…
Triple-well ferroelectricity and kagome-like Chern flat band in two-dimensional multiferroic CuVPSe
Brian Anchico, Jingyi Duan, Haojie Sun +3
Two-dimensional multiferroics that host nontrivial topological bands offer a rich platform for correlated and tunable quantum phenomena, yet such materials remain rare. Here, using…
Evidence of Mott Insulator with Thermally Induced Melting Behavior in Kagome Compound Nb3Cl8
Qiu Yang, Min Wu, Jingyi Duan +12
The kagome lattice provides a playground to explore novel correlated quantum states due to the presence of flat bands in its electronic structure. Recently discovered layered kagom…
Ultrafast symmetry modulation and induced magnetic excitation in the Kagome metal RbV3Sb5
Mengxue Guan, Xiaodong Zhou, Jingyi Duan +8
Light-matter interaction in frustrated Kagome metals enables access to hidden quantum states, yet the microscopic origin of symmetry breaking under ultrafast excitation remains elu…
Symmetry Classification of Altermagnetism and Emergence of Type-IV Magnetism in Two Dimensions
Mu Tian, Chaoxi Cui, Zeying Zhang +3
Two-dimensional (2D) magnetism, particularly 2D altermagnetism (AM), has attracted considerable interest due to its exceptional physical properties and broad application potential.…
Quantized Spin-Hall Conductivity in Altermagnet FeTeO with Mirror-Spin Coupling
Run-Wu Zhang, Chaoxi Cui, Yang Wang +3
Due to spin-orbit coupling (SOC), crucial for the quantum spin Hall (QSH) effect, a quantized spin-Hall conductivity has not yet been reported in QSH insulators and other realistic…
