Study finds single photons cannot exceed the speed of light
Nano-LEDs emit full visible spectrum of light
Researchers analyze the future of transistor-less magnonic logic circuits
Physicists Propose Method for Entangling Moving Material Particles
Nonlinear light-generating zero-index metamaterial created
(Phys.org) —The Information Age will get a major upgrade with the arrival of quantum processors many times faster and more powerful than today's supercomputers. For the benefits of this new Information ...
Fantastic phonons: Blocking sound, channeling heat with 'unprecedented precision'
Imagine living on a bustling city block, but free from the noise of car horns and people on the street. The emerging field of phononics could one day make this a reality.
Wagon-wheel pasta shape for better LED: 'Rotelle' molecules depolarize light more efficiently than 'spaghetti'
One problem in developing more efficient organic LED light bulbs and displays for TVs and phones is that much of the light is polarized in one direction and thus trapped within the light-emitting diode, or ...
Researchers find way to measure speed of spinning object using light's orbital angular momentum
New phenomenon could lead to novel types of lasers and sensors
There are several ways to "trap" a beam of light—usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method ...
Researchers discover way to allow 80 percent of sound to pass through walls
Ferroelectric-graphene-based system could lead to improved information processing
Researchers at MIT have proposed a new system that combines ferroelectric materials—the kind often used for data storage—with graphene, a two-dimensional form of carbon known for its exceptional electronic ...
Researchers develop metamaterials able to control spread of light
New kind of cosmic flash may reveal something never seen before: Birth of a black hole
(Phys.org) —When a massive star exhausts its fuel, it collapses under its own gravity and produces a black hole, an object so dense that not even light can escape its gravitational grip. According to a ...
Physicists find right (and left) solution for on-chip optics
(Phys.org) —A Harvard-led team of researchers has created a new type of nanoscale device that converts an optical signal into waves that travel along a metal surface. Significantly, the device can recognize ...
