Chiral Dirac-like fermion in spin-orbit-free antiferromagnetic semimetals
Pengfei Liu, Ao Zhang, Jingzhi Han +1
Dirac semimetal is a phase of matter, whose elementary excitation is described by the relativistic Dirac equation. In the limit of zero mass, its parity-time symmetry enforces the…
Spin-group symmetry in magnetic materials with negligible spin-orbit coupling
Pengfei Liu, Jiayu Li, Jingzhi Han +2
Symmetry formulated by group theory plays an essential role with respect to the laws of nature, from fundamental particles to condensed matter systems. Here, by combining symmetry…

A van der Waals antiferromagnetic topological insulator with weak interlayer magnetic coupling
Chaowei Hu, Xiaoqing Zhou, Pengfei Liu +11
Magnetic topological insulators (TI) provide an important material platform to explore quantum phenomena such as quantized anomalous Hall (QAH) effect and Majorana modes, etc. Thei…
Symmetry-assisted protection and compensation of hidden spin polarization in centrosymmetric systems
Yingjie Zhang, Pengfei Liu, Hongyi Sun +2
It is recently noted that in certain centrosymmetric compounds, spin-orbit interaction couples each local sector that lacks inversion symmetry and thus leads to visible spin polari…
