Topological acoustic interface states in one-dimensional (1D) acoustic topological insulators
(ATIs) are zero-dimensional (0D) topological states localized at an interface. Unlike …

Rapidly developing photonics brings many interesting resonant optical phenomena, in
which the Fano resonance (FR) always intrigues researchers because of its applications in …

The Fano resonance, as a phenomenon of wave scattering, is based on the interaction
between a “bright mode” and a “dark mode” giving rise to an asymmetric and ultrasharp …

Fragile topology (FT) opens a new direction in topological photonics, but a new type of
photonic crystal (PC) with FT remains to be proposed. In this Letter, the double-site …

In this paper, we obtain acoustic topological insulators with acoustic pseudospin and
topological boundary states by breaking the symmetry of lattice structure with local and …

In this paper, the stepless space-regulation of topological acoustic transmission channels
with high fault tolerance is proposed through introducing structural defect dislocations into a …

Exceptional points (EPs) as branch singularities describe peculiar degeneracies of non-
Hermitian systems, widely studied in topological and non-topological optical architectures …

Acoustic topological insulators (ATIs) are known to own topologically protected properties
similar to their electronic and optical counterparts. However, for the topological insulators …

Growing interest in acoustic topological insulators arises from their robust edge states, which
are resistant to defects and backscattering. Traditionally, the edge states of topological …

Integrated nanophotonic biosensors offer a promising route toward future biomedical
detection applications that may enable inexpensive, portable, and sensitive diagnosis of …
