Topological acoustics is an emerging field that lies at the intersection of condensed matter
physics, mechanical structural design and acoustics engineering. It explores the design and …

There are two prominent applications of the mathematical concept of topology to the physics
of materials: band topology, which classifies different topological insulators and semimetals …

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 …

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 …

With growing environmental and ecological concerns, innovative energy storage systems
are urgently required to develop smart grids and electric vehicles (EVs). Since their …

There has been a significant focus on real topological systems that enjoy space‐time
inversion symmetry and lack spin‐orbit coupling. While the theoretical classification of the …

Conspectus Bismuth-based research has become a highly topical field in recent years,
yielding remarkable prospects for new fundamental insights and new materials applications …

Symmetry-protected topological crystalline insulators (TCIs) have primarily been
characterized by their gapless boundary states. However, in time-reversal-(T-) invariant …

Topological phases of matter are ubiquitous in crystals, but less is known about their
existence in amorphous systems, that lack long-range order. We review the recent progress …

Möbius-ring resonators stem from a well-studied and fascinating geometrical structure which
features a one-sided topology, the Möbius strip, and have been shown to exhibit fermion …
