Editor's note: This talk was filmed and uploaded by the volunteers who organized this TEDx event; speakers and topics are  Topological Insulators (TIs) are a new class of materials that have a band gap in the bulk that is spin-orbit locked i.e.

They are characterized by a full insulating gap in the bulk and gapless edge or surface states which are protected by time-reversal symmetry. These topological materials have been theoretically predicted and experimentally observed in a variety of Abstract. A topological insulator is a material with an insulating interior but time-reversal symmetry-protected conducting edge states. Since its prediction and discovery almost a decade ago, such a symmetry-protected topological phase has been explored beyond electronic systems in the realm of photonics. Topological materials in general, and topological insulators in particular, can be defined by physically measurable topological invariants in topological field theories.

PHYS598PTD A.J.Leggett 2013 Lecture 21 Topological insulators: preliminaries 1 Topological insulators: preliminaries1 At least as far as currently known, a good qualitative understanding of the properties of the class of materials now known as topological insulators (TI’s) can be achieved on the Topological insulators possess edge states protected from disorder and can be realized in real materials as well as in synthetic materials based on optical, acoustic or mechanical characteristics the ordinary insulator from “weak” and “strong” topological insulators. These phases are characterized by the presence of gapless surface or edge states. In the two-dimensional quantum spin-Hall phase and the three-dimensional strong topological insulator, these states are robust and are insensitive to weak disorder and interactions. Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have protected conducting states on their edge or surface. These states are possible due to the combination of spin-orbit interactions and time-reversal symmetry.

It belongs to the long-ranged entangled Topological Order by the definition of X.G.Wen of MIT, but it is still a part of theory of Invertible Topological Quantum Field Theory (of Dan Freed, see References and papers by him) with its partition Two-and-a-half years ago, Charles Kane and Eugene Mele received the 2019 Breakthrough Prize in Fundamental Physics.The award recognized their theories that predicted the existence of topological insulators, a new class of material with the unique property of being an electrical insulator on the inside and having a surface that conducts electricity. 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 the bulk and gapless edge or surface states which are protected by time-reversal symmetry. These topological materials have been theoretically predicted and experimentally observed in a variety of Abstract.

The bulk of such materials is insulating but the surface can conduct electric current with well-defined spin texture. The award recognized their theories that predicted the existence of topological insulators, a new class of material with the unique property of being an electrical insulator on the inside and having a surface that conducts electricity. There are few mistakes in the equations and the physical explanations behind topological insulators are forgotten throughout a vast quantity of equations - however, this may be a reflex of some difficulty of the author to express himself in English.

Topological insulators have non-trivial symmetry-protected topological order; however, having a conducting surface is not unique to topological insulators, since ordinary band insulators can also support conductive surface states.

Three-dimensional (3D) topological insulators are characterized by the presence of an odd number of families of Dirac fermions—ideally one- at each of their surfaces. A topological insulator is a material whose surface is conductive but whose inside is not. While that may sound pretty straightforward, guess again. There’s no obvious reason why a material of uniform structure should display such different properties in different parts. Topological insulators correspond to insulating materials whose valence bands possess non-standard topological properties.
