These lecture notes are mainly concerned with how the concept of topological insulators is generalized when interactions are included. More generally, the interplay of symmetry and topology is discussed. Traditionally, phases of matter were distinguished on the basis of symmetry alone.

Challenge

This course-based primer provides newcomers to the field with a concise introduction to some of the core topics in the emerging field of topological insulators. The aim is to provide a basic understanding of edge states, bulk topological invariants, and of the bulk--boundary correspondence with as simple mathematical tools as possible.

Topological Insulator Surface States and Electrical Transport.

This chapter indicates the placing of lecture notes on the subject of topological insulators and superconductors by Shoucheng Zhang from Stanford University. The lecture notes were not supplied for the text so do not appear here. Keywords: topical insulators, superconductors.

Solution

This course introduces topology, covering topics fundamental to modern analysis and geometry. It also deals with subjects like topological spaces and continuous functions, connectedness, compactness, separation axioms, and selected further topics such as function spaces, metrization theorems, embedding theorems and the fundamental group.


Note that the gapless surface states of topological insulators differ from those in the quantum Hall effect: the gapless surface states of topological insulators are symmetry-protected (i.e., not topological), while the gapless surface states in quantum Hall effect are topological (i.e., robust against any local perturbations that can break all the symmetries).

Results

This book provides an introduction to topological matter with a focus on insulating bulk systems. A number of prerequisite concepts and tools are first laid out, including the notion of symmetry transformations, the band theory of semiconductors and aspects of electronic transport.

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.

The basic band structure of a topological insulator is that of a normal insulator, with the Fermi level lying between the conduction and valence bands (see diagram). However, at the surface of the material, there are electron states with energies falling within the bulk energy gap; these are free to move and thus allow conduction. The mechanism behind this phenomenon is very complex, but is.
