As for topological insulators, topological semimetals can exist in various numbers of dimensions and with different symmetries, and they all have surface states.In particular, superconducting systems with nodes can have flat bands on their surface [26–29 Topological insulators are a new state of quantum matter with a bulk gap and odd number of relativistic Dirac fermions on the surface. The bulk of such materials is insulating but the surface can conduct electric current with well-defined spin texture. A similar idea underpins topological insulators, but the transformation in this case doesn’t involve a material’s spatial properties. Instead, it concerns the wavefunctions of the electrons flowing in the material. These contain what is in effect a knot, making it impossible to smoothly convert a topological insulator into a normal insulator. Whereas electrons usually have a mass, in the case of topological insulators the conducting electrons on the surface have no mass and are automatically "spin polarized," leading to the unique half-integer quantum Hall effect observed and also making the material promising for various potential applications.

alloy is a strong topological insulator in the 1;111 Z 2 topological class. We go on to develop general arguments which show that spatial symmetries lead to additional topological structure of the bulk energy bands, and impose further constraints on the surface band structure. Inversion-symmetric band structures are characterized by eight Z

They are characterized by having bulk electronic states like that of a standard band gap insulator but with spin-momentum locked conduction channels only at the surface of the material. Topological insulators are a game-changing class of materials; charged particles can flow freely on their edges and route themselves around defects, but can't pass through their interiors.

topological insulators subject to time-reversal symmetry breaking are discussed. In section 5, we review several methods of plasmon excitation. In section 6, we draw attention to some open questions and the future applications of plasmonics in topological insulators. 2. Plasmons on the surfaces of bulk topological insulators

To date, TIs have been realized to be a promising modulator not only for fiber lasers but also for solid state lasers. In this chapter the electronic and optical properties of TIs have been reviewed. In this video, Zahid Hasan of Princeton University in the US describes why topological insulators could lead to high-performance electronics and applications in quantum computing. This video is part of our 100 Second Science series, in which researchers give concise presentations covering the spectrum of physics.

Whereas electrons usually have a mass, in the case of topological insulators the conducting electrons on the surface have no mass and are automatically "spin polarized," leading to the unique half-integer quantum Hall effect observed and also making the material promising for various potential applications. For the strong topological insulator, the odd number of crossings depicted in Fig. 13 (b) persists when the unit cell is doubled.
