A conventional topological insulator (TI) has gapped bulk states but gapless edge states.
The emergence of the gapless edge states is dictated by the bulk topological invariant of the …

Topological materials discovery has evolved at a rapid pace over the past 15 years following
the identification of the first nonmagnetic topological insulators (TIs), topological crystalline …

Nontrivial topological surface states (TSSs), which possess extraordinary carrier mobility
and are protected by the bulk symmetry, have emerged as an innovative platform to search …

Using a recently developed formalism called topological quantum chemistry, we perform a
high-throughput search of 'high-quality'materials (for which the atomic positions and …

Topological quantum chemistry and symmetry-based indicators have facilitated large-scale
searches for materials with topological properties at the Fermi energy (EF). We report the …

Over the past decade, topological materials—in which the topology of electron bands in the
bulk material leads to robust, unconventional surface states and electromagnetism—have …

In recent years, transition metal dichalcogenides (TMDs) have garnered great interest as
topological materials. In particular, monolayers of centrosymmetric β-phase TMDs have …

Low-dimensional van der Waals materials have been extensively studied as a platform with
which to generate quantum effects. Advancing this research, topological quantum materials …

Bismuth (Bi) is a topological crystalline insulator (TCI), which has gapless topological
surface states (TSSs) protected by a specific crystalline symmetry that strongly depends on …

A second-order topological insulator (SOTI) in d spatial dimensions features topologically
protected gapless states at its (d-2)-dimensional boundary at the intersection of two crystal …
