Spin Splitter without Spin-Split Bands: A Reconfigurable Altermagnetic Texture
Bin Xi, Jie Lu, Qiang Luo +4
The altermagnetic spin-splitter effect converts an electric field into a transverse pure spin current, with no net magnetization and no charge-Hall counterpart. In established mate…
Crossover and Changeover in Spin-1 Kitaev- Chain with Uniaxial Single-ion Anisotropy
Qiang Luo, Shijie Hu, Wang Yang +4
Recent advances in bond-directional spin chains have revealed extensive emergent phenomena and unconventional criticality. Here we investigate the spin-1 Kitaev- chain with uni…
Beyond-adiabatic flat Chern bands from a double-helix skyrmion crystal
Bin Xi, Ken Chen, Qiang Luo +4
A central challenge in flat-band engineering is suppressing kinetic energy without sacrificing Berry curvature. We show that a double-helix skyrmion crystal (DHSKX)--two sublattice…
Successive topological phase transitions in two distinct spin-flop phases on the honeycomb lattice
Xudong Li, Jize Zhao, Jinbin Li +1
The Kitaev magnets with bond-dependent interactions have garnered considerable attention in recent years for their ability to harbor exotic phases and nontrivial excitations. The t…
