Topological materials have become the focus of intense research in recent years, since they
exhibit fundamentally new physical phenomena with potential applications for novel devices …

The topological phases in materials have been studied in recent decades for their unique
boundary states and transport properties. Photonic systems with band structures embrace …

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 …

Topological electronic materials such as bismuth selenide, tantalum arsenide and sodium
bismuthide show unconventional linear response in the bulk, as well as anomalous gapless …

The interplay between symmetry and topology leads to a rich variety of electronic topological
phases, protecting states such as the topological insulators and Dirac semimetals. Previous …

We present a method for efficiently enumerating all allowed, topologically distinct, electronic
band structures within a given crystal structure in all physically relevant dimensions. The …

We propose MnBi 2 n Te 3 n+ 1 as a magnetically tunable platform for realizing various
symmetry-protected higher-order topology. Its canted antiferromagnetic phase can host …

We theoretically study three-dimensional topological semimetals (TSMs) with nodal lines
protected by crystalline symmetries. Compared to TSMs with point nodes, eg, Weyl …

We study the bulk-boundary correspondence for topological crystalline phases, where the
crystalline symmetry is an order-two (anti) symmetry, unitary or antiunitary. We obtain a …

The rich variety of crystalline symmetries in solids leads to a plethora of topological
crystalline insulators (TCIs), featuring distinct physical properties, which are conventionally …
