Topological insulators and superconductors have recently become one of the most actively studied subfields in condensed matter physics. A clever application of topology to the theory of electronic structure gave an impetus to the synthesis of new materials, which are now under active experimental investigation. On the theoretical side, the notion of a topologically protected surface state provides a new challenge for the theory of localization and raises many fundamental questions about the interplay of topology, disorder, and electron-electron interactions. Topological insulators also represent a class of symmetry-protected topologically ordered phase. Last but not least, the appearance of non-Abelian anyons when topological insulators are proximity-coupled to superconductors makes them an exciting platform for fault-tolerant quantum computing.
