Majorana fermion
2014-10-04 08:36:22

Chuck Bednar for redOrbit.com - Your Universe Online Scientists from Princeton University have discovered an unusual new type of particle that is essentially its own antiparticle – behaving simultaneously like matter and antimatter, according to a new study currently appearing in the online edition of the journal Science. The particle, which is known as a Majorana fermion, was detected and imaged using a two-story-tall microscope floating in an ultralow-vibration lab, the researchers...

dark matter AMS

Chuck Bednar for redOrbit.com – Your Universe Online Thanks to a particle detector module mounted to the exterior of the International Space Station (ISS), researchers from the MIT Laboratory for Nuclear Science and their colleagues have collected new measurements which could help scientists learn more about the origin and characteristics of dark matter. The unit, known as the Alpha Magnetic Spectrometer (AMS), captures incoming cosmic rays from throughout the galaxy. Out of about 41...

World’s First Photonic Router
2014-07-14 03:14:29

Weizmann Institute of Science Weizmann Institute scientists take another step down the long road toward quantum computers Weizmann Institute scientists have demonstrated for the first time a photonic router – a quantum device based on a single atom that enables routing of single photons by single photons. This achievement, as reported in Science magazine, is another step toward overcoming the difficulties in building quantum computers. At the core of the device is an atom that can...

Laser-like Beams That Use 250x Less Power
2014-06-06 03:56:27

By Nicole Casal Moore, University of Michigan With precarious particles called polaritons that straddle the worlds of light and matter, University of Michigan researchers have demonstrated a new, practical and potentially more efficient way to make a coherent laser-like beam. They have made what's believed to be the first polariton laser that is fueled by electrical current as opposed to light, and also works at room temperature, rather than way below zero. Those attributes make the...

Pamela Fleming, spokesperson of The Institute for Basic Research, Palm Harbor, Florida, has released an open letter to the Directors of Cern laboratories in Geneva, Switzerland, containing unchallenged technical arguments showing that their ongoing test of the gravity of antimatter via alleged "anti-Hydrogen atoms" may be basically flawed, and requesting due scientific process on alternative more resolutory tests (http://www.i-b-r.org/G-Veneziano-denunciation.htm). New York,...

Joint Quantum Institute Sending entangled beams through fast-light materials Michael Lewis's bestselling book "Flash Boys" describes how some brokers, engaging in high frequency trading, exploit fast telecommunications to gain fraction-of-a-second advantage in the buying and selling of stocks. But you don't need to have billions of dollars riding on this-second securities transactions to appreciate the importance of fast signal processing. From internet to video streaming, we want...

Turning Light Into Matter: Scientists Say 80-Year-Old Theory Is Provable
2014-05-19 08:30:22

Lawrence LeBlond for redOrbit.com - Your Universe Online First theorized in 1934 by a pair of scientists – Gregory Breit and John Wheeler – turning light into matter was deemed a fantastical and equally impossible feat. By smashing two photons together at a high rate of speed, the scientists hypothesized that it could create an electron and a positron. An occurrence of such magnitude was deemed extremely rare and difficult to reproduce. So rare that it has never been observed in any...

HADES Experiments Searching For Dark Matter
2014-05-13 03:30:32

Helmholtz-Zentrum Dresden-Rossendorf Although Dark Energy and Dark Matter appear to constitute over 95 percent of the universe, nobody knows of which particles they are made up. Astrophysicists now crossed one potential Dark Matter candidate – the Dark Photon or U boson – off the list in top position. This is the result of recent HADES experiments, where researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and from 17 other European institutes try to pin down the nature of...

Quantum Computing Advances At MIT - Trapping Rubidium Atoms In A Lattice Of Light
2014-04-11 04:29:35

redOrbit Staff & Wire Reports - Your Universe Online Scientists at MIT and Harvard University have developed a light lattice that traps atoms, a technique they say could aid in the creation of powerful quantum computing systems. The researchers used a laser to place individual atoms of the metal rubidium near the surface of a lattice of light, allowing them to couple a lone atom with a single photon, or light particle. The system allows both the atom and photon to switch the quantum...

Quantum Photon Properties Revealed In Another Particle, The Plasmon
2014-04-04 15:46:00

Jessica Stoller-Conrad, California Institute of Technology For years, researchers have been interested in developing quantum computers—the theoretical next generation of technology that will outperform conventional computers. Instead of holding data in bits, the digital units used by computers today, quantum computers store information in units called "qubits." One approach for computing with qubits relies on the creation of two single photons that interfere with one another in a device...
