Quantum Dots Brighten the Future of Lighting
May 8, 2012 — Researchers have boosted the efficiency of a novel source of white light called quantum dots more than tenfold, making them of potential interest for commercial ... > full story -
Billiard Game in an Atom: Physicists Trace Double Ionization of Argon Atoms on Attosecond Time Scales
May 8, 2012 — Physicists have traced the double ionization of argon atoms on attosecond time scales. When an intense laser pulse interacts with an atom it generates agitation on the micro scale. The most likely ... > full storyMore: -
First Light: Researchers Develop New Way to Generate Superluminal Pulses
May 3, 2012 — Researchers have developed a novel way of producing light pulses that are "superluminal" -- in some sense they travel faster than the speed of light. The new method could be used to improve the ... > full story -
Simulating Reality: Less Memory Required on Quantum Computer Than on Classical Computer, Study Shows
May 3, 2012 — Simulations of reality would require less memory on a quantum computer than on a classical computer, new research has shown. The study demonstrates a new way in which computers based on quantum ... > full story -
Fast, Low-Power, All-Optical Switch
May 3, 2012 — A new solid-state device uses one beam of light to switch another beam of light from one direction to another. It uses one-fifth the power -- only 90 atto-joules -- than the previous all-optical ... > full story -
2012 Football Helmet Ratings: Two More Added to the 5 Star Mark, Experts Say
May 1, 2012 — Virginia Tech released the results of its 2012 rating for adult football helmets that is designed to assess a helmet’s ability to reduce the risk of concussion.A total of three helmets achieved ... > full story -
Redefining Time: Extremely Precise Clock Signals Transmitted Over Long Distances
April 30, 2012 — Scientists have successfully sent a highly accurate clock signal across the many hundreds of kilometers of countryside that separate two ... > full story -
Single Nanomaterial Yields Many Laser Colors
April 29, 2012 — Engineers have created nanoscale single crystals that can produce the red, green, or blue laser light needed in digital displays. The size determines color, but all the pyramid-shaped quantum dots ... > full story -
Electron Politics: Physicists Probe Organization at the Quantum Level
April 25, 2012 — "Quantum critical points" (QCP) in exotic electronic materials can act much like polarizing "hot button issues" in an election. On either side of the QCP, electrons fall into line and behave as ... > full story -
Physicists Benchmark Quantum Simulator With Hundreds of Qubits
April 25, 2012 — Physicists have built a quantum simulator that can engineer interactions among hundreds of quantum bits (qubits) -- 10 times more than previous devices. The simulator has passed a series of important ... > full story
