Non-altermagnetic spin texture in MnTe
Meng Zeng, Pengfei Liu, Ming-Yuan Zhu +19
Recently, altermagnets have emerged as promising candidates in spintronics, uniquely combining large spin-polarized electronic states with zero net magnetization. A prominent examp…
Topological Charge Quadrupole Protected by Spin-Orbit U(1) Quasi-Symmetry in Antiferromagnet NdBiPt
Ao Zhang, Xiaobing Chen, Jiayu Li +3
The interplay of symmetry and topology in crystal solids has given rise to various elementary excitations as quasiparticles. Among these, those with significant Berry-phase-related…
Observation of Spin Splitting in Room-Temperature Metallic Antiferromagnet CrSb
Meng Zeng, Ming-Yuan Zhu, Yu-Peng Zhu +18
Recently, unconventional antiferromagnets that enable the splitting of electronic spins have been theoretically proposed and experimentally realized, where the magnetic sublattices…
Catalog of Unconventional Magnons in Collinear Magnets
Xiaobing Chen, Yuntian Liu, Pengfei Liu +5
Topological magnons have garnered significant interest for their potential in both fundamental research and device applications, owing to their exotic, uncharged, yet topologically…
Enumeration and representation theory of spin space groups
Xiaobing Chen, Jun Ren, Yanzhou Zhu +7
Those fundamental physical properties, such as phase transitions, Weyl fermions, and spin excitation, in all magnetic ordered materials, were ultimately believed to rely on the sym…
