An equivalent expression of Z2 Topological Invariant for band insulators using Non-Abelian Berry's connection
Rui Yu, Xiao Liang Qi, Andrei Bernevig +2
We introduce a new expression for the Z2 topological invariant of band insulators using non- Abelian Berry's connection. Our expression can identify the topological nature of a gen…

Topological Aspect and Quantum Magnetoresistance of -AgTe
Wei Zhang, Rui Yu, Wanxiang Feng +4
To explain the unusual non-saturating linear magnetoresistance observed in silver chalcogenides, the quantum scenario has been proposed based on the assumption of gapless linear en…
