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 …

Efficient nonlinear optical interactions are essential for many applications in modern
photonics. However, they typically require intense laser sources and long interaction …

Structures with near-zero parameters (for example, media with near-zero relative permittivity
and/or relative permeability, and thus a near-zero refractive index) exhibit a number of …

The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

This review focuses on the physics of optical excitation dynamics, band gap engineering
and charge carrier dynamics in metal-halide perovskites and their organic hybrids as well as …

The discovery, design and development of materials are critically linked to advances in
many areas of research, and optics is no exception. Recently, the spectral region in which …

High‐performance uncooled photodetectors operating in the long‐wavelength infrared and
terahertz regimes are highly demanded in the military and civilian fields …

Abstract Epsilon‐near‐zero (ENZ) photonics is the study of light–matter interactions in the
presence of structures with near‐zero permittivity and has been emerging as an important …

The single-particle and many-body properties of twisted bilayer graphene (TBG) can be
dramatically different from those of a single graphene layer, particularly when the two layers …

Plasmonics is a rapidly develo** field at the boundary of physical optics and condensed
matter physics. It studies phenomena induced by and associated with surface plasmons …
