Bernevig and Hughes have made some of the most important theoretical contributions to this young field and this timely volume will have significant staying power. 2021-01-20 · Most natural and artificial materials have crystalline structures from which abundant topological phases emerge1–6. 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.

logical superconductor the edge-states are Majorana modes and have potential applications in quantum computation. Meanwhile, in a topological insulator the

To address this subject, we adopt the linear coupling geometry of the Su-Schrieffer-Heeger model, a paradigmatic example for a topological insulator, and render it nonlinearly in the context of superconducting circuits. As a consequence, the system exhibits topologically It moves on to explain topological phases of matter such as Chern insulators, two- and three-dimensional topological insulators, and Majorana p-wave wires.
