Multiple Symmetry-Protected Dirac Nodal Lines in A Quasi-One-Dimensional Semimetal
Zhanyang Hao, Weizhao Chen, Yuan Wang +23
Nodal-line semimetals (NLSMs) contains Dirac/Weyl type band-crossing nodes extending into shapes of line, loop and chain in the reciprocal space, leading to novel band topology and…

Koopmans' theorem as the mechanism of nearly gapless surface states in self-doped magnetic topological insulators
Weizhao Chen, Yufei Zhao, Qiushi Yao +2
The magnetization-induced gap at the surface state is widely believed as the kernel of magnetic topological insulators (MTIs) because of its relevance to various topological phenom…
