Scalar Spin Chiral Order via Bond Selectivity in Strained Collinear Ferrimagnets
Xin Liu, Li Ma, Mingyue Zhao +10
Scalar spin chirality (SSC) drives a series of topological transports in noncoplanar magnets. However, the ordering temperature of magnet hosting intrinsic SSC order is typically b…

Symmetry-Based Real-Space Framework for Realizing Flat Bands and Unveiling Nodal-Line Touchings
Rui-Heng Liu, Xin Liu
Flat band (FB) systems provide ideal playgrounds for studying correlation physics, whereas multi-orbital characteristics in real materials are distinguished from most simple FB mod…

Non-Abelian line graph: A generalized approach to flat bands
Rui-Heng Liu, Xin Liu
Flat bands (FBs) in materials can enhance the correlation effects, resulting in exotic phenomena. Line graph (LG) lattices are well known for hosting FBs with isotropic hoppings in…
