'Super atoms': Rydberg excitations form ordered structures in a quantum gas due to long-range interactions
(Phys.org)—Future computers are expected to use the laws of quantum physics to accomplish certain tasks in the blink of an eye that require decades for present-day computers. Physicists at the Max Planck ...
Tabletop laser-like device creates coherent multicolor beams of ultraviolet, T- and X-rays
For the first time, researchers have produced a coherent, laser-like, directed beam of light that simultaneously streams ultraviolet light, X-rays, and all wavelengths in between.
Chandra finds nearest pair of supermassive black holes
(PhysOrg.com) -- Astronomers have used NASA's Chandra X-ray Observatory to discover the first pair of supermassive black holes in a spiral galaxy similar to the Milky Way. At a distance of 160 million light ...

Nano antenna concentrates light: Intensity increases 1,000-fold
(PhysOrg.com) -- Everybody who's ever used a TV, radio or cell phone knows what an antenna does: It captures the aerial signals that make those devices practical. A lab at Rice University has built an antenna ...
Researchers discover mechanism that helps humans see in bright and low light
Ever wonder how your eyes adjust during a blackout? When we go from light to near total darkness, cells in the retina must quickly adjust. Vision scientists at Washington University School of Medicine in St. ...
Rapid data transfer thanks to quantum physics
RUB engineers have developed a new concept for accelerating data transfer in server farms. To this end, the team at the Chair of Photonics and Terahertz Technology applies a quantum-mechanical variable, i.e. ...
Switching on a dime: How plants function in shade and light
Photosynthesis is the process by which plants convert energy from the sunlight into chemical energy in the form of sugars. These sugars are used by plants to grow and function, as well as food for animals ...
Engineers find a way to win in laser performance by losing
Energy loss in optical systems, such as lasers, is a chief hindrance to their performance and efficiency, and it occurs on an ongoing, frustrating basis.
Arctic study sheds light on tree-ring divergence problem
Changes in tree-ring density in the Arctic may be evidence of changes in light intensity during the trees' growth, according to a new study by San Francisco State University researcher Alexander Stine.
