New Evidence To Help In Search For Charge 'Stripes' In Superconductors
2013-09-03 11:17:10

Brookhaven National Laboratory Findings identify signature that will help scientists investigate and understand materials that carry current with no resistance Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have identified a series of clues that particular arrangements of electrical charges known as "stripes" may play a role in superconductivity—the ability of some materials to carry electric current with no energy loss. But uncovering the detailed...

Quantum Inverted Pendulum
2013-08-28 08:18:43

Georgia Institute of Technology A simple pendulum has two equilibrium points: hanging in the "down" position and perfectly inverted in the "up" position. While the "down" position is a stable equilibrium, the inverted position is definitely not stable. Any infinitesimal deviation from perfectly inverted is enough to cause the pendulum to eventually swing down. It has been known for more than 100 years, though, that an inverted pendulum can be stabilized by vibrating the pivot point....

Researchers Discover Atomic Clock Can Simulate Quantum Magnetism
2013-08-09 11:33:49

National Institute of Standards and Technology (NIST) Researchers at JILA have for the first time used an atomic clock as a quantum simulator, mimicking the behavior of a different, more complex quantum system. Atomic clocks now join a growing list of physical systems that can be used for modeling and perhaps eventually explaining the quantum mechanical behavior of exotic materials such as high-temperature superconductors, which conduct electricity without resistance. All but the...

Thinner shadow masks with smaller holes advance testing on energy efficient computing. Lanham, MD (PRWEB) August 07, 2013 Potomac Photonics, a leader in micro hole drilling technology, has recently completed a project making shadow masks for work leading to energy efficient computing at the Massachusetts Institute of Technology in Cambridge, MA. With ever increasing energy consumption demands placed on microelectronics, R&D groups worldwide have turned to developing novel technologies...

Resonance In 'Artificial Atoms' Control Quantum Communication
2013-08-06 12:26:15

University of Copenhagen - Niels Bohr Institute Researchers at the Niels Bohr Institute, together with colleagues in the US and Australia, have developed a method to control a quantum bit for electronic quantum communication in a series of quantum dots, which behave like artificial atoms in the solid state. The results have been published in the scientific journal Physical Review Letters. In a conventional computer, information is made up of bits, comprised of 0's and 1's. In a quantum...

Light Transistor Developed By TU Vienna
2013-07-08 10:08:30

Vienna University of Technology TU Vienna has managed to turn the oscillation direction of beams of light -- simply by applying an electrical current to a special material. This way, a transistor can be built that functions with light instead of electrical current. Light can oscillate in different directions, as we can see in the 3D cinema: Each lens of the glasses only allows light of a particular oscillation direction to pass through. However, changing the polarization direction of...

2 orders for electrons A German-French research team has constructed a new model that explains how the so-called pseudogap state forms in high-temperature superconductors. The calculations predict two coexisting electron orders. Below a certain temperature, superconductors lose their electrical resistance and can conduct electricity without loss. "It is not to be excluded that the new pseudogap theory also provides the long-awaited explanation for why, in contrast to conventional metallic...

New Quantum Technologies Enabled With Spintronics Approach
2013-06-04 16:20:51

University of Chicago A team of researchers, including members of the University of Chicago´s Institute for Molecular Engineering, highlight the power of emerging quantum technologies in two recent papers published in the Proceedings of the National Academy of Sciences. These technologies exploit quantum mechanics, the physics that dominates the atomic world, to perform disparate tasks such as nanoscale temperature measurement and processing quantum information with lasers. The two...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
