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…
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…
Chiral Dirac fermion in a collinear antiferromagnet
Ao Zhang, Ke Deng, Jieming Sheng +18
In a Dirac semimetal, the massless Dirac fermion has zero chirality, leading to surface states connected adiabatically to a topologically trivial surface state as well as vanishing…
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…
Role of hidden spin polarization in non-reciprocal transport of antiferromagnets
Weizhao Chen, Mingqiang Gu, Jiayu Li +2
The discovery of hidden spin polarization (HSP) in centrosymmetric nonmagnetic crystals, i.e., spatially distributed spin polarization originated from local symmetry breaking, has…
Designing light-element materials with large effective spin-orbit coupling
Jiayu Li, Qiushi Yao, Lin Wu +4
Spin-orbit coupling (SOC), the core of numerous condensed-matter phenomena such as nontrivial band gap, magnetocrystalline anisotropy, etc, is generally considered to be appreciabl…
