Topological insulators and superconductors

- X. Qi, Shou-Cheng Zhang
- Physics
- 12 August 2010

Topological insulators are new states of quantum matter which cannot be adiabatically connected to conventional insulators and semiconductors. They are characterized by a full insulating gap in the… Expand

Topological insulators in Bi2Se3, Bi2Te3 and Sb2Te3 with a single Dirac cone on the surface

- Haijun Zhang, C. 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… Expand

Topological field theory of time-reversal invariant insulators

- X. Qi, T. Hughes, Shou-Cheng Zhang
- Physics
- 24 February 2008

We show that the fundamental time-reversal invariant (TRI) insulator exists in $4+1$ dimensions, where the effective-field theory is described by the $(4+1)$-dimensional Chern-Simons theory and the… Expand

Quantum Spin Hall Effect and Topological Phase Transition in HgTe Quantum Wells

- B. Bernevig, T. Hughes, Shou-Cheng Zhang
- Physics, Medicine
- Science
- 15 November 2006

We show that the quantum spin Hall (QSH) effect, a state of matter with topological properties distinct from those of conventional insulators, can be realized in mercury telluride–cadmium telluride… Expand

Quantum Spin Hall Insulator State in HgTe Quantum Wells

- M. König, S. Wiedmann, +5 authors Shou-Cheng Zhang

Model Hamiltonian for topological insulators

- C. 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… Expand
