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.

19 Dec 2019 The so-called topological insulators are those materials that are insulators With technological applications in mind, for example in information
One such advancement is the topological insulator, a new phase of matter that stands on the boundary between insulation and conductance. This technology would allow for the eventual construction of the quantum computer, a revolutionary device that would use the dynamics of atomic-scale objects to store and manipulate information. Topological insulator (TI), a promising quantum and semiconductor material, has gapless surface state and narrow bulk band gap.
The most promising applications of topological insulators are spintronic devices and dissipationless transistors for quantum computers based on the quantum Hall effect [13] and quantum anomalous Hall effect. [51] In addition, topological insulator materials have also found practical applications in advanced magnetoelectronic and optoelectronic

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.

Topological insulators have attracted much interest recently from Condensed Matter Physics as well as the wider scientific community. 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.

Nonetheless, the sur-face states of a 3D topological insulator do strongly resemble the edge states of a 2D topological insulator. As in the 2D case, the direction of electron motion The topological insulator (TI) is a new phase of matter that exhibits quantum-Hall-like properties, even in the absence of an external magnetic field. Understanding and characterizing unique properties of these materials can lead to many novel applications, such as current induced magnetization or extremely robust quantum memory bits.
