Ever since its discovery the notion of Berry phase has permeated through all branches of
physics. Over the past three decades it was gradually realized that the Berry phase of the …

This article reviews recent theoretical and experimental advances in the fundamental
understanding and active control of quantum fluids of light in nonlinear optical systems. In …

Recent progress in understanding the topological properties of condensed matter has led to
the discovery of time-reversal-invariant topological insulators. A remarkable and useful …

<? pag\vskip-16pt?> Harnessing linear and angular momenta of light is one of the
cornerstones in modern optics and has found tremendous applications in optical circuits …

Optical metamaterials have presented an innovative method of manipulating light.
Hyperbolic metamaterials have an extremely high anisotropy with a hyperbolic dispersion …

Light carries both spin and orbital angular momentum. These dynamical properties are
determined by the polarization and spatial degrees of freedom of light. Nano-optics …

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 …

The spin Hall effect (SHE) of light is very weak because of the extremely small photon
momentum and spin-orbit interaction. Here, we report a strong photonic SHE resulting in a …

We have detected a spin-dependent displacement perpendicular to the refractive index
gradient for photons passing through an air-glass interface. The effect is the photonic …

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 …
