One-dimensional quasiperiodic systems, such as the Harper model and the Fibonacci
quasicrystal, have long been the focus of extensive theoretical and experimental research …

Quasiperiodic lattices have recently been shown to be a nontrivial topological phase of
matter. Charge pum**—one of the hallmarks of topological states of matter—was recently …

This is a comprehensive theoretical survey of acoustic wave propagation in layered
materials including elastic, viscoelastic and piezoelectric layers. The phonon modes are …

We investigate the topological properties of Fibonacci quasicrystals using cavity polaritons.
Composite structures made of the concatenation of two Fibonacci sequences allow one to …

Introducing an axis of reflection symmetry in a quasicrystal leads to the creation of localised
edge modes that can be used to build waveguides. We develop theory that characterises …

We provide theoretical and experimental evidence for the existence of topological Tamm
states at the interface between two stubbed photonic crystals (PCs) as a function of the …

A simple photonic device consisting of two dangling side resonators grafted at two sites on a
waveguide is designed in order to obtain sharp resonant states inside the transmission gaps …

We demonstrate analytically and numerically the possibility of existence of the analogues of
electromagnetic induced transparency (EIT) and electromagnetic induced reflection (EIR) in …

Topological phonon polaritons (TPhPs) are localized boundary modes arising from the
combination of topological photonics and phonon polaritons in micro/nanostructures made …
