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,...

Tabletop Particle Accelerator Laser Light Does Not Have To Be As Powerful
2014-05-29 05:07:42

redOrbit Staff & Wire Reports - Your Universe Online Creating your own tabletop particle accelerator just got a little bit easier, according to scientists from the Lawrence Berkeley National Laboratory (Berkeley Lab), who report that the laser lights used in these miniature units do not have to be as precise as previously believed. When most people think of particle accelerators, things like the Large Hadron Collider that was used in the discovery of the Higgs boson come to mind....

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...

Laser Light Waves Needs More Bass
2014-05-21 03:31:46

Florian Aigner, Vienna University of Technology They shed light on atomic and molecular processes: ultrashort laser pulses are required to study extremely fast quantum phenomena. For years, scientists have been trying to tune the shape of light waves so as to, for instance, steer an electron on exactly the right path. At the TU Vienna, an extraordinarily powerful new method to influence the shape of the laser light wave has been developed in cooperation with the Imperial College in London...

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...

Ecole Polytechnique Fédérale de Lausanne Magnetic devices like hard drives, magnetic random access memories (MRAMs), molecular magnets, and quantum computers depend on the manipulation of magnetic properties. In an atom, magnetism arises from the spin and orbital momentum of its electrons. 'Magnetic anisotropy' describes how an atom's magnetic properties depend on the orientation of the electrons' orbits relative to the structure of a material. It also provides directionality and...

DOE/Brookhaven National Laboratory Findings unequivocally link 2 'personality' changes of electrons at critical point Scientists seeking to understand the intricacies of high-temperature superconductivity—the ability of certain materials to carry electrical current with no energy loss—have been particularly puzzled by a mysterious phase that emerges as charge carriers are added that appears to compete with superconductivity. It's also been a mystery why, within this "pseudogap"...

The Cathode Ray Tube, which has internal or external means to accelerate and deflect electron beams, is a vacuum tube containing an electron gun and a fluorescent screen. The electron beams that are deflected are used to create images in the form of light emitted from the fluorescent screen. The CRT works by using an evacuated glass envelope which is large, deep, heavy, and relatively fragile. Ferdinand Braun is credited with the first CRT in 1897. It can also be known as the Braun tube....

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
