Light in a spin: Researchers demonstrate angular accelerating light
Light must travel in a straight line and at a constant speed, or so the laws of nature suggest. Now, researchers at the University of the Witwatersrand in Johannesburg have demonstrated that laser light traveling along a ...

New metasurface laser produces world's first super-chiral light
Researchers have demonstrated the world's first metasurface laser that produces "super-chiral light": light with ultra-high angular momentum. The light from this laser can be used as a type of "optical spanner" to or for ...

The shapes of galaxies
Since Edwin Hubble proposed his galaxy classification scheme in 1926, numerous studies have investigated the physical mechanisms responsible for the shapes of spiral and elliptical galaxies. Because the processes are complex, ...

Boomerang-like beams of light: Research makes progress toward observing quantum backflow in two dimensions
Researchers at the University of Warsaw's Faculty of Physics have superposed two light beams twisted in the clockwise direction to create anti-clockwise twists in the dark regions of the resultant superposition. The results ...

Researchers offer theoretical description of topological water wave structures
Topological wave structures are wave patterns that exhibit specific topological properties, or in other words, properties that remain unvaried under smooth deformations of a physical system. These structures, such as vortices ...
Electron 'pairing': Triplet superconductivity proven experientially for first time
Researchers at Ruhr-Universitat Bochum, Christian-Albrechts-Universitat zu Kiel and Santa Barbara have made the first experimental breakthrough in quantum physics: Their studies on the "pairing behavior" of electrons have ...
