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 ...

Since man first looked up to the sky, the moon has been one of the most fascinating and admired celestial bodies. It appears ...

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 ...

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 ...

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 ...

Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the Poisson spot to create stable patterns of light called optical skyrmions, ...

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 ...

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 ...

Controlling the spin degree of freedom of light at the microscale is crucial for advancing photonic information processing. Spin-polarized light propagation, combined ...

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 ...
