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 progress in utilizing ultrafast light-matter interaction to control the macroscopic
properties of quantum materials is reviewed. Particular emphasis is placed on photoinduced …

Two-dimensional (2D) materials including graphene, transition metal dichalcogenides, black
phosphorus, MXenes, and semimetals have attracted extensive and widespread interest …

As elemental main group materials (ie, silicon and germanium) have dominated the field of
modern electronics, their monolayer 2D analogues have shown great promise for next …

In this brief review, we summarize and elaborate on some of the nomenclature of polaritonic
phenomena and systems as they appear in the literature on quantum materials and …

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

The birth of terahertz imaging approximately coincides with the birth of the journal Optics
Express. The 20^ th anniversary of the journal is therefore an opportune moment to consider …

Semiconductor plasmonics has become a frontier for light manipulation beyond the
diffraction limit, offering a broader spectral range and higher flexibility of plasmon …

Abstract 2D layered materials with atomic thickness have attracted extensive research
interest due to their unique physicochemical and electronic properties, which are usually …

The field of terahertz science and technology has been an active and thriving research area
for several decades. However, the field has recently experienced an inflection point, as …
