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 …

The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

The original Kerker effect was introduced for a hypothetical magnetic sphere, and initially it
did not attract much attention due to a lack of magnetic materials required. Rejuvenated by …

The spin Hall effect (SHE) of light, as an analogue of the SHE in electronic systems, is a
promising candidate for investigating the SHE in semiconductor spintronics/valleytronics …

We review basic physics and novel types of optical angular momentum. We start with a
theoretical overview of momentum and angular momentum properties of generic optical …

Advanced photonic nanostructures are currently revolutionizing the optics and photonics
that underpin applications ranging from light technology to quantum-information processing …

Scientists have known for more than a century that light possesses both linear and angular
momenta along the direction of propagation. However, only recent advances in optics have …

The paper briefly presents some essential concepts and features of light fields with strong
spatial inhomogeneity of amplitude, phase, polarization, and other parameters. It contains a …

Metamaterials are artificial optical media composed of sub-wavelength metallic and
dielectric building blocks that feature optical phenomena not present in naturally occurring …

Topological photonics is a rapidly emerging field of research in which geometrical and
topological ideas are exploited to design and control the behavior of light. Drawing …
