Topological insulators and superconductors
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 theExpand
Topological insulators in Bi2Se3, Bi2Te3 and Sb2Te3 with a single Dirac cone on the surface
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 statesExpand
Topological field theory of time-reversal invariant insulators
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 theExpand
Quantum Spin Hall Effect and Topological Phase Transition in HgTe Quantum Wells
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 tellurideExpand
Quantum Spin Hall Insulator State in HgTe Quantum Wells
TLDR
The quantum phase transition at the critical thickness, d = 6.3 nanometers, was independently determined from the magnetic field–induced insulator-to-metal transition, providing experimental evidence of the quantum spin Hall effect. Expand
Model Hamiltonian for topological insulators
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) andExpand
Experimental Observation of the Quantum Anomalous Hall Effect in a Magnetic Topological Insulator
TLDR
The observation of the quantum anomalous Hall (QAH) effect in thin films of chromium-doped (Bi,Sb)2Te3, a magnetic topological insulator shows a plateau in the Hall resistance as a function of the gating voltage without any applied magnetic fields, signifying the achievement of the QAH state.

Quantized Anomalous Hall Effect in Magnetic Topological Insulators
TLDR
A realization of a quantum anomalous Hall system is proposed by magnetically doping thin films of three-dimensional topological insulators and calculating the effects of various dopants and film thicknesses, which are predicted to have long-range ferromagnetic order, potentially joining dilute magnetic semiconductors as candidates for spintronic applications.

Inducing a Magnetic Monopole with Topological Surface States
TLDR
It is proposed that this effect can be used to experimentally realize a gas of quantum particles carrying fractional statistics, consisting of the bound states of the electric charge and the image magnetic monopole charge. Expand
