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 …

Bound states in the continuum (BICs) have attracted attention in photonics owing to their
interesting properties. For example, BICs can effectively confine light in a counterintuitive …

Despite their widespread use for performing advanced computational tasks, digital signal
processors suffer from several restrictions, including low speed, high power consumption …

The topological properties of an object, associated with an integer called the topological
invariant, are global features that cannot change continuously but only through abrupt …

The study of classical wave physics has been reinvigorated by incorporating the concept of
the geometric phase, which has its roots in optics, and topological notions that were …

Bound states in the continuum (BICs) confine resonances embedded in a continuous
spectrum by eliminating radiation loss. Merging multiple BICs provides a promising …

The concept of topological energy bands and their manifestations have been demonstrated
in condensed matter systems as a fantastic paradigm toward unprecedented physical …

A bound state in the continuum (BIC) is a localized state of an open structure with access to
radiation channels, yet it remains highly confined with, in theory, an infinite lifetime and …

The advancement in electromagnetic metamaterials, which commenced three decades ago,
experienced a rapid transformation into acoustic and elastic systems in the forms of …

By engineering an anti-parity-time (anti-PT) symmetric cavity magnonics system with precise
eigenspace controllability, we observe two different singularities in the same system. One …
