insulators, allowing for the distinction between ordinary and topological insulators (TIs) [4–6]. In the bulk, like any other ordinary insulator, a TI exhibits an energy band gap separating the valance and conduction bands. However, contrary to normal insulators, TIs support conductive gapless states ﬂowing along their edges.

The story of the topological insulator began with the discovery of the quantum spin Hall effect (QSH) in 1980. QSH was the first example of a quantum state with spontaneously broken symmetry, meaning it comprises of a symmetric probability distribution where any pair of outcomes has the same probability of occurring.

The basic concepts, model Hamiltonians, and novel electronic properties of these new topological materials are explained. 2018-10-16 · A topological insulator (TI) is a band insulator in the bulk featuring metallic edge or surface states which are topologically protected against elastic single-particle back-scattering (Qi and Zhang 2011). The term 'topological insulator' is often used or meant synonymously with 'time-reversal invariant TI'. Topological insulators are of high scientific interest as they are promising candidates for spintronic applications.

We review two-dimensional topological insulators whose one-dimensional edge states are char-acterized by spin-momentum locking and protected by time-reversal symmetry. We focus in particular on their transport properties in the presence of electron interac-
