Observation of hidden altermagnetism in CsVTeO
Guowei Yang, Ruihan Chen, Changchao Liu +25
Altermagnets are characterized by anisotropic band/spin splittings in momentum space, dictated by their spin-space group symmetries. However, the real-space modulations of altermag…

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…
