New math bridges holography and twistor theory

The modern-day theoretical physicist faces a taxing uphill climb. "As we learn more, reality becomes ever more subtle; the absolute becomes relative, the fixed becomes dynamical, the definite is laden with uncertainty," writes ...

Holography approach improves heads up displays for planes and cars

Heads-up displays are transparent devices used in airplanes and cars to provide information such as critical flight data or driving directions on the windshield. An innovative holography-based approach could soon make these ...

With laser light, scientists create first X-ray holographic images of viruses

Holography, like photography, is a way to record the world around us. Both use light to make recordings, but instead of two-dimensional photos, holograms reproduce three-dimensional shapes. The shape is inferred from the ...

Physicists tune a spin diode

A team of physicists at MIPT has offered a new design of a spin diode, placing the device between two kinds of antiferromagnetic materials. By adjusting the orientation of their antiferromagnetic axes, it is possible to change ...

Nanoparticle gel controls twisted light with magnetism

"Help me, Obi Wan Kenobi. You're my only hope." For many of those around at the release of Star Wars in 1977, that scene was a first introduction to holograms—a real technology that had been around for roughly 15 years.

Black holes with 'dreadlocks' offer insight into quantum matter

Physicists understand little about quantum matter, which is a building block of future quantum computers. Theorists have now discovered that black holes with 'dreadlocks' harbor a similarly exotic order pattern, which makes ...
