Metasurfaces are ultra-thin assemblies of subwavelength structures engineered to manipulate light at the nanoscale. When designed from materials with strong optical nonlinearity, these planar ...

Researchers at the Würzburg site of the Cluster of Excellence ctd.qmat have succeeded in transferring the topological quantum Hall and spin Hall effects to a hybrid light-matter system by harnessing ...

Across the world, there are naturally occurring optical illusions that captivate spectators. Cloud formations can sometimes make it seem like there's an ocean or a UFO in the sky. Whether it is salt ...

A new study from the University of Eastern Finland (UEF) explores the behavior of photons, the elementary particles of light, as they encounter boundaries where material properties change rapidly over ...

The science behind natural optical phenomena—colors in the sky, rainbows, halos, coronas, iridescence, glories, glitter patterns and auroras—will be the topic of a free talk at Rochester Institute of ...

Magneto-optical phenomena in X-ray and neutron scattering encompass a suite of techniques that exploit the interaction between electromagnetic radiation or neutron beams and the magnetic structure of ...

Roughly every 15 years, Earth passes through the plane of Saturn’s rings, causing them to nearly disappear from view — not to mention generating a variety of other interesting phenomena. The next such ...

Every once in a while, you may look up towards the Sun and see strange bright lights on either side of it. Or perhaps you’ll be sitting in an aircraft, looking out the window at its shadow and see a ...

Optical illusions occur naturally in different habitats and conditions across the world. Cloud formations can sometimes make it seem like there's an ocean or a UFO in the sky. Whether it is salt flats ...

Researchers have successfully transferred the topological quantum Hall and spin Hall effects to a hybrid light-matter system using targeted material design. (Nanowerk News) In a groundbreaking advance ...
