(Wang&Zhang PRX, 2, 031008) This is a general framework instead of a single formula. It is applicable to many different topological insulators and superconductors. A topological insulator is a material that behaves as an insulator in its interior but whose surface contains conducting states, meaning that electrons can only move along the surface of the material. 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.

Loss-Free Charge Transport without Superconductivity? Loss-free currents have furthermore been found to flow along the edges of topological insulators.

These fall into the category of "higher-order" topological insulators and superconductors which possess surface states that propagate along one-dimensional curves (hinges) or are localized at some points (corners) on the surface. We can think of topological insulators (superconductors) as being gapped states (thus “insulators”) in d spatial dimensions (we consider here d = 1, 2, 3) with the following property: if we terminate the topological insulator (superconductor) against a “topologically trivial” state, such as e.g. simply vacuum, gapless degrees of freedom will necessarily appear at the interface It moves on to explain topological phases of matter such as Chern insulators, two- and three-dimensional topological insulators, and Majorana p-wave wires. Additionally, the book covers zero modes on vortices in topological superconductors, time-reversal topological superconductors, and topological responses/field theory and topological indices.

The book begins with simple concepts such as Berry phases, Dirac fermions, Hall conductance and its link to topology, and the Hofstadter problem of lattice

The bulk materials are described by non-interacting single particle band Hamiltonians with a finite excitation gap. Topological Insulators and Superconductors I.

Summary and Outlook - What we have accomplished - Challenges for the Topological insulators (superconductors) are inherently “holographic” states: the nature of the d-dimensional gapped topological bulk state can be read off from the (holographic) ‘‘image’’ or ‘‘shadow’’ of these topological properties on the system’s boundaries. Indeed, there is a one-to-one correspondence between the Within a given class, the different topological sectors can be distinguished, depending on the case, by a Z or a Z_2 topological invariant. This is an exhaustive classification. Here we construct representatives of topological insulators and superconductors for all five classes and in arbitrary spatial dimension d, in terms of Dirac Hamiltonians. Using these representatives we demonstrate how topological insulators (superconductors) in different dimensions and different classes can be This graduate-level textbook is the first pedagogical synthesis of the field of topological insulators and superconductors, one of the most exciting areas of research in condensed matter physics. Presenting the latest developments, while providing all the calculations necessary for a self-contained and complete description of the discipline, it is ideal for graduate students and researchers However, for a spin-singlet pairing superconductor with d xy symmetry, zero-energy surface states, differently from the case of regular high-T c cuprates, are now Majorana fermions, and the tunneling conductance for a junction is now strongly dependent on the magnetization direction, due to the proximity of the topological insulator.

Topological superconductors have a full pairing gap in the bulk and gapless surface states consisting of Majorana fermions. The theory of topological superconductors is reviewed, in close analogy to the theory of topological insulators.

Topological Insulators and Topological Superconductors will provide graduate students and researchers with the physical understanding and mathematical tools needed to embark on research in this rapidly evolving field. ASJC Scopus subject areas Physics and Astronomy (all) Link to publication in Scopus 2010-06-17 · GENERAL SCIENTIFIC SUMMARY Introduction and background. A topological insulator is an insulator that has exotic metallic states on its boundary when placed next to vacuum. Similarly, a topological superconductor is a fully gapped superconductor that has delocalized Andreev surface states. In this review, we discuss recent progress in the explorations of topological materials beyond topological insulators; specifically, we focus on topological crystalline insulators and bulk topological superconductors. The basic concepts, model Hamiltonians, and novel electronic properties of these new topological materials are explained. This graduate-level textbook is the first pedagogical synthesis of the field of topological insulators and superconductors, one of the most exciting areas of research in condensed matter physics.
