Topological insulators in Bi2Se3, Bi2Te3 and Sb2Te3 with a single Dirac cone on the surface
- Haijun Zhang, Chaoxing Liu, X. Qi, X. Dai, Z. Fang, Shou-Cheng Zhang
- Physics
- 1 June 2009
Topological insulators are new states of quantum matter in which surface states residing in the bulk insulating gap of such systems are protected by time-reversal symmetry. The study of such states…

Dirac semimetal and topological phase transitions in A 3 Bi ( A = Na , K, Rb)
- Zhijun Wang, Yan Sun, Z. Fang
- Physics, Materials Science
- 25 February 2012
Three-dimensional (3D) Dirac point, where two Weyl points overlap in momentum space, is usually unstable and hard to realize. Here we show, based on the first-principles calculations and effective…
Three-dimensional Dirac semimetal and quantum transport in Cd3As2
- Zhijun Wang, H. Weng, Quansheng Wu, X. Dai, Z. Fang
- Physics

Model Hamiltonian for topological insulators
- Chaoxing Liu, X. Qi, Haijun Zhang, X. Dai, Z. Fang, Shou-Cheng Zhang
- Physics
- 10 May 2010
In this paper we give the full microscopic derivation of the model Hamiltonian for the three-dimensional topological insulators in the Bi(2)Se(3) family of materials (Bi(2)Se(3), Bi(2)Te(3) and…
Weyl Semimetal Phase in Noncentrosymmetric Transition-Metal Monophosphides
- H. Weng, C. Fang, Z. Fang, Andrei Bernevig, X. Dai
- Physics
- 31 December 2014
Based on first-principle calculations, we show that a family of nonmagnetic materials including TaAs, TaP, NbAs, and NbP are Weyl semimetals (WSM) without inversion centers. We find twelve pairs of…
