Coulomb Drag in Altermagnets
Hao-Jie Lin, Song-Bo Zhang, Hai-Zhou Lu +1
An altermagnet is a newly discovered antiferromagnet, characterized by unique anisotropic spin-split energy bands. It has attracted tremendous interest, because of its promising po…
Discovery of a topological exciton insulator with tunable momentum order
Md Shafayat Hossain, Tyler A. Cochran, Yu-Xiao Jiang +27
Correlated topological materials often maintain a delicate balance among physical symmetries: many topological orders are symmetry protected, while most correlated phenomena arise…
Floating Edge Bands in the Bernevig-Hughes-Zhang model with Altermagnetism
Yang-Yang Li, Song-Bo Zhang
Floating edge bands (FEB) have been identified in systems such as obstructed atomic insulators and layered nonsymmorphic semimetals, attracting considerable interest recently. Here…
Van-Hove annihilation and nematic instability on a Kagome lattice
Yu-Xiao Jiang, Sen Shao, Wei Xia +20
Novel states of matter arise in quantum materials due to strong interactions among electrons. A nematic phase breaks the point group symmetry of the crystal lattice and is known to…
