Topological insulators (superconductors) are gapped phases of non-interacting fermions which exhibit topologically protected boundary modes. These boundary states are gapless,

The bulk materials are described by non-interacting single particle band Hamiltonians with a finite excitation gap. Topological Insulators and Superconductors I. Topological Insulators and Band Theory Unifying theme: bulk –boundary correspondence - Integer Quantum Hall Effect - 2D Quantum Spin Hall Insulator - 3D Topological Insulator - Topological Superconductivity, Majorana fermions II. 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.

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 preparing to work in this area, and it will be an essential reference both within and outside the

However, the bulk–edge correspondence—which has been widely used in 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. The two-dimensional (2D) topological insulator is a quantum spin Hall insulator, which is a close cousin of the integer quantum Topological insulators and superconductors Learning goals • We know the Kane Mele model.
