Journal ArticleDOI
Coupled spin and valley physics in monolayers of MoS2 and other group-VI dichalcogenides.
TL;DR: It is shown that inversion symmetry breaking together with spin-orbit coupling leads to coupled spin and valley physics in monolayers of MoS2 and other group-VI dichalcogenides, making possible controls ofspin and valley in these 2D materials.
Journal ArticleDOI
Quantum spin Hall effect in silicene and two-dimensional germanium.
TL;DR: It is demonstrated that silicene with topologically nontrivial electronic structures can realize the quantum spin Hall effect (QSHE) by exploiting adiabatic continuity and the direct calculation of the Z(2) topological invariant.
Journal ArticleDOI
Quantum anomalous Hall effect in graphene from Rashba and exchange effects
Zhenhua Qiao,Shengyuan A. Yang,Wanxiang Feng,Wang-Kong Tse,Jun Ding,Yugui Yao,Yugui Yao,Jian Wang,Qian Niu +8 more
TL;DR: In this paper, the authors investigated the possibility of realizing quantum anomalous Hall effect in graphene and showed that a bulk energy gap can be opened in the presence of both Rashba spin-orbit coupling and an exchange field.
Journal ArticleDOI
Half-Heusler compounds as a new class of three-dimensional topological insulators.
Di Xiao,Yugui Yao,Yugui Yao,Wanxiang Feng,Jun Wen,Wenguang Zhu,Wenguang Zhu,Xing-Qiu Chen,G. Malcolm Stocks,Zhenyu Zhang,Zhenyu Zhang,Zhenyu Zhang +11 more
TL;DR: A definitive proof of the strained LaPtBi as a 3DTI is provided by directly calculating the topological Z2 invariants in systems without inversion symmetry.
Journal ArticleDOI
Large anomalous Hall effect in a half-Heusler antiferromagnet
Takehito Suzuki,Robin Chisnell,Aravind Devarakonda,Y.-T. Liu,Wanxiang Feng,Di Xiao,Jeffrey W. Lynn,Joseph Checkelsky +7 more
TL;DR: In this article, the anomalous Hall effect is found in topologically non-trivial half-Heusler antiferromagnets thanks to Berry phase effects associated with symmetry breaking.
