Orbital-selective band evolution and out-of-plane correlation in the FeGe-family kagome antiferromagnet ScFeGe
Jae Hyuck Lee, Ze Yan, Tongrui Li +10
In strongly correlated materials such as high-temperature superconductors, the relation between charge density wave (CDW) order and magnetism remains an important unresolved proble…
Termination-Dependent Surface States and Magnetic Fingerprints of Chiral Helimagnet Cr1/3TaS2
Bo Liang, Xue Li, Congcong Le +36
Chiral helimagnets based on intercalated transition-metal dichalcogenides, characterized by nano-scale spin ordering, provide a powerful route to engineer chiral spin textures (e.g…
Multiple Topological States in LaAgAs2, a Failed Square-Net Semimetal
Yang Liu, Tongrui Li, Xixi Yuan +15
The rational design of new materials emerges as an important direction to explore new topological materials, which is based on the understanding of the correlation between crystal…
Unusual Dual Flat Bands and two-dimensional Dirac-node Arc State in Kagome Metal Ni3In2S2
Bo Liang, Yichen Liu, Jie Pang +36
Kagome materials are at the frontier of condensed matter physics. An ideal kagome lattice features only one geometrically frustrated flat band spanning the entire momentum space an…
Surface reconstruction and orthogonal decoupling in SrAl4 and EuAl4
Tongrui Li, Leiyuan Chen, Jian Yuan +10
Surface-induced symmetry breaking in quantum materials can stabilize exotic electronic phases distinct from those in the bulk, yet its momentum-space manifestations remain elusive…
Orbital-selective charge transfer drives two-step negative thermal expansion structural transitions in PbTa2Se4
Peng Li, Xiaohui Yang, Wenhua Song +7
The negative thermal expansion (NTE) effect has been found generally combined with structural phase transitions. However, the charge and orbital freedoms of the NTE has not been we…
