Entangled Photons Created from Quantum Dots
November 18, 2009 — To exploit the quantum world to the fullest, a key commodity is entanglement -- the spooky, distance-defying link that can form between objects such as atoms even when they are completely shielded ... > full story -
Sculptured Materials Allow Multiple Channel Plasmonic Sensors
November 15, 2009 — Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if ... > full story -
Invisibility Visualized: New Software for Rendering Cloaked Objects
November 13, 2009 — Scientists and curiosity seekers who want to know what a partially or completely cloaked object would look like in real life can now get their wish -- virtually. Scientists have created a new ... > full story -
Quantum Gas Microscope Offers Glimpse Of Quirky Ultracold Atoms
November 12, 2009 — Physicists have created a quantum gas microscope that can be used to observe single atoms at temperatures so low the particles follow the rules of quantum mechanics, behaving in bizarre ways. The ... > full story -
Unexpected Properties Of Nanostructures: When Holes Obscure The View
November 12, 2009 — Metals are opaque: they reflect light almost completely. For that reason they are utilized as mirrors; as films deposited onto a glass -- you find them in any bathroom. If the metal film is very ... > full story -
Laser-Plasma Accelerators Ride On Einstein's Shoulders
November 11, 2009 — Using Einstein's theory of special relativity to speedup computer simulations, scientists have designed laser-plasma accelerators with energies of 10 billion electron volts (GeV) and beyond. These ... > full story -
New Nano Color Sorters From Molecular Foundry
November 11, 2009 — Researchers have created bowtie-shaped antennae that function as the first tunable nano color sorters, able to capture, filter and steer light at the ... > full story -
Vibrations Key To Efficiency Of Green Fluorescent Protein
November 11, 2009 — Green fluorescent protein has invaded thousands of research labs around the world, thanks to its versatility in labeling cells and organisms. Now, chemists have discovered why GFP is such an ... > full story -
Flipping A Photonic Shock Wave
November 10, 2009 — Physicists have directly observed a reverse shock wave of light in a specially tailored structure known as a left-handed metamaterial. Although it was first predicted over forty years ago, this is ... > full story -
Lasers Put A Shine On Metals
November 9, 2009 — Polishing metal surfaces is a demanding but monotonous task, and it is difficult to find qualified young specialists. Polishing machines do not represent an adequate alternative because they cannot ... > full story
