Researchers from the University of East Anglia, working with partners in South Africa, have shown that light can twist and spin in empty space without mirrors, lenses, or special materials. By ...

Scientists at the University of East Anglia have uncovered a hidden property of light that allows it to twist, spin and ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them ...

Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field rotates. The other comes from the shape of the wavefront itself, which can ...
