Journal ArticleDOI
Classification of topological insulators and superconductors in three spatial dimensions
TL;DR: In this paper, the authors systematically studied topological phases of insulators and superconductors in three dimensions and showed that there exist topologically nontrivial (3D) topologically nonsmooth topological insulators in five out of ten symmetry classes introduced in the context of random matrix theory.
Journal ArticleDOI
Classification of topological quantum matter with symmetries
TL;DR: In this article, a review of the classification schemes of both fully gapped and gapless topological materials is presented, and a pedagogical introduction to the field of topological band theory is given.
Journal ArticleDOI
Topological insulators and superconductors: Tenfold way and dimensional hierarchy
TL;DR: In this paper, the authors constructed representatives of topological insulators and superconductors for all five classes and in arbitrary spatial dimension d, in terms of Dirac Hamiltonians.

Topological insulators and superconductors: ten-fold way and dimensional hierarchy
TL;DR: In this paper, the authors constructed representatives of topological insulators and superconductors for all five classes and in arbitrary spatial dimension d, in terms of Dirac Hamiltonians, using these representatives they demonstrate how topologically insulators (superconductors) in different dimensions and different classes can be related via dimensional reduction by compactifying one or more spatial dimensions.
Journal ArticleDOI
Ca 3 P 2 and other topological semimetals with line nodes and drumhead surface states
TL;DR: In this paper, the authors derived the invariants that guarantee the stability of the line nodes in the bulk under reflection symmetry and showed that a quantized Berry phase (i.e., a ${\mathbb{Z}}_{2}$ invariant) leads to the appearance of protected surfaces states, which take the shape of a drumhead.
