Polaritons are hybrid excitations of matter and photons. In recent years, polaritons in van der
Waals nanomaterials—known as van der Waals polaritons—have shown great promise to …

Recent research in topological photonics has not only proposed and realized novel
topological phenomena such as one‐way broadband propagation and robust transport of …

Over the past decade, topology has emerged as a major branch in broad areas of physics,
from atomic lattices to condensed matter. In particular, topology has received significant …

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 …

Polaritons, originating from the interactions between photons and material excitations, have
attracted attention because of their strong field compression and deeply subdiffractional …

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 …

Plasmon polaritons are hybrid excitations of light and mobile electrons that can confine the
energy of long-wavelength radiation at the nanoscale. Plasmon polaritons may enable many …

Interactions between light and matter play an instrumental role in spectroscopy, sensing,
quantum information processing and lasers. In most of these applications, light is considered …

Resonant cavities are essential building blocks governing many wave-based phenomena,
but their geometry and reciprocity fundamentally limit the integration of optical devices. We …

Graphene is an atomically thin plasmonic medium that supports highly confined plasmon
polaritons, or nano-light, with very low loss. Electronic properties of graphene can be …
