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 …

Phononic crystals (PnCs) control the transport of sound and heat similar to the control of
electric currents by semiconductors and metals or light by photonic crystals. Basic and …

This fully updated second edition of The Physics of Phonons remains the most
comprehensive theoretical discussion devoted to the study of phonons, a major area of …

The last 20 years have witnessed growing impacts of the topological concept on the
branches of physics, including materials, electronics, photonics, and acoustics. Topology …

Optomechanical systems provide a pathway for the bidirectional optical-to-microwave
interconversion in (quantum) networks. These systems can be implemented using hybrid …

Recently published discoveries of acoustic-and optical-mode inversion in the phonon
spectrum of certain metals became the first realistic example of noninteracting topological …

Phonons play a key role in the physical properties of materials, and have long been a topic
of study in physics. While the effects of phonons had historically been considered to be a …

We review distinct features arising from the unique nature of the carrier-phonon coupling in
self-assembled semiconductor quantum dots. Because of the discrete electronic energy …

We achieve interface states with a high reflectance in photonic heterostructures composed
of two kinds of all-dielectric one-dimensional photonic crystals (1DPCs) with symmetric unit …
