The photonic spin Hall effect (SHE) refers to the transverse spin separation of photons with
opposite spin angular momentum, after the beam passes through an optical interface or …

The quantum spin Hall effect lays the foundation for the topologically protected manipulation
of waves, but is restricted to one-dimensional-lower boundaries of systems and hence limits …

Whenever a quantum system undergoes a cyclic evolution governed by a slow change of
parameters, it acquires a phase factor: the geometric phase. Its most common formulations …

Optical superoscillations are rapid, subwavelength spatial variations of the intensity and
phase of light, occurring in complex electromagnetic fields formed by the interference of …

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 …

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 …
