Unconventional spin textures emerging from a universal symmetry theory of spin-momentum locking
Yuntian Liu, Jiayu Li, Pengfei Liu +1
Spin textures, i.e., the distribution of spin polarization vectors in reciprocal space, exhibit diverse patterns determined by symmetry constraints, resulting in a variety of spint…

Chern-insulator phase in antiferromagnets
Yuntian Liu, Jiayu Li, Qihang Liu
The long-sought Chern insulators that manifest quantum anomalous Hall effect are typically considered to occur solely in ferromagnets. Here, we theoretically predict the realizabil…

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…
