Diffusion driven by temperature or concentration gradients is a fundamental mechanism of
energy and mass transport that inherently differs from wave propagation in both physical …

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 …

Topological photonics has attracted increasing attention in recent years due to the unique
opportunities it provides to manipulate light in a robust way immune to disorder and defects …

Abstract In 1878, Lord Rayleigh observed the highly celebrated phenomenon of sound
waves that creep around the curved gallery of St Paul's Cathedral in London,. These …

Topological photonics has emerged as a promising field in photonics that is able to shape
the science and technology of light. As a significant degree of freedom, valley is introduced …

Photonic and phononic topological insulators (TIs) offer numerous opportunities for
manipulating light and sound with high efficiency and resiliency. On the other hand, inverse …

We present the new concept of photonic alloy as a nonperiodic topological material. By
mixing nonmagnetized and magnetized rods in a nonperiodic 2D photonic crystal …

Topological elastic metamaterials have emerged as a new frontier in the quest of topological
phases in condensed matter physics. Their exotic topological properties open a wealth of …

Topological nanophotonics is a new avenue for exploring nanoscale systems from visible to
THz frequencies, with unprecedented control. By embracing their complexity and fully …

Motivated by the recent experimental realizations of hyperbolic lattices in circuit quantum
