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.

### 2020-07-23 · Two dimensional (2D) topological insulators (TIs) and topological superconductors (TSCs) have been intensively studied for recent years due to their great potential for dissipationless electron transportation and fault-tolerant quantum computing, respectively. Here we focus on stanene, the tin analogue of graphene, to give a brief review of their development as a candidate for both 2D TI and

eISBN: 978-1-4008-4673-3. Subjects: Physics. 2021-04-19 · Topological insulators have stimulated intense interests in condensed-matter physics, optics, acoustics and mechanics, usually with a focus on the spin degree of freedom. Topological insulators are new states of quantum matter which can not be adiabatically connected to conventional insulators and semiconductors.

The bulk materials are described by non-interacting single particle band Hamiltonians with a finite excitation gap.

### 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.
