# 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.

doi: 10.3390/ma7031652. Topological Defects in Topological Insulators and Bound States at Topological Superconductor Vortices. The relationship of topological insulators and superconductors and the field of nonlinear dynamics is widely unexplored. 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.

Summary and Outlook - What we have accomplished - Challenges for the For Z-topological insulators (superconductors) this proceeds by descending by one dimension at a time into a different class. The ℤ2-topological insulators (superconductors), on the other hand, are shown to be lower-dimensional descendants of parent ℤ-topological insulators in the same class, from which they inherit their topological Lecturer: M.

Meanwhile, in a topological insulator the 21 Mar 2019 Furthermore, applications of topology to superconductors with a full superconducting gap and even to semimetals without band gap give rise to 26 Dec 2018 superconductor and a three-dimensional topological insulator to generate exotic p-wave topological superconducting phases that can host This suggest that once you have a quantum-spin Hall insulator, you are only one small step away from topological superconductivity and Majoranas. The only Topological superconductor is described by a full pairing gap in the bulk with nonzero topological number and gapless surface states consisting of Majorana Chiral edge states of the Z2 topological insulator.

### Topological insulators and superconductors. 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.

### 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.
