Researchers Investigate Light Tsunamis In A Superconductor
2013-04-03 16:03:51

Helmholtz Association of German Research Centres In their latest experiment, Prof. Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter at the Hamburg-based Center for Free-Electron Laser Science (CFEL) and Dr. Michael Gensch from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) investigated together with other colleagues from the HZDR, the United Kingdom, and Japan if and how superconductivity can be systematically controlled. The objective of their...

To engineers, it´s a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists at the University of Illinois and the University of Pennsylvania found that for copper-containing superconductors, known as cuprates, electrons are not enough to carry the current. “The story of electrical conduction in metals is told entirely in terms of electrons.  The cuprates show that there is something completely new to be understood beyond...

Weizmann Institute researchers suggest one can affect an atom´s spin by adjusting the way it is measured One of the most basic laws of quantum mechanics is that a system can be in more than one state — it can exist in multiple realities — at once. This phenomenon, known as the superposition principle, exists only so long as the system is not observed or measured in any way. As soon as such a system is measured, its superposition collapses into a single state. Thus, we, who...

Surprising Control Over Photoelectrons From A Topological Insulator
2013-03-13 15:22:44

Lawrence Berkeley National Laboratory Berkeley Lab scientists discover how a photon beam can flip the spin polarization of electrons emitted from an exciting new material Plain-looking but inherently strange crystalline materials called 3D topological insulators (TIs) are all the rage in materials science. Even at room temperature, a single chunk of TI is a good insulator in the bulk, yet behaves like a metal on its surface. Researchers find TIs exciting partly because the electrons...

A multi-university team of researchers has artificially engineered a unique multilayer material that could lead to breakthroughs in both superconductivity research and in real-world applications. The researchers can tailor the material, which seamlessly alternates between metal and oxide layers, to achieve extraordinary superconducting properties – in particular, the ability to transport much more electrical current than non-engineered materials. The team includes experts from the...

New Technique Could Reveal High Detail Of Earth's Composition
2013-02-22 10:50:16

April Flowers for redOrbit.com - Your Universe Online In a new study recently published in the journal Science, a research team from Amherst College and The University of Texas at Austin has described a new technique that might one day reveal the composition and characteristics of the deep Earth in never before seen detail. There's just a tiny little hitch in the new technique. It relies on a fifth force of nature that has not yet been detected. Current physics theories hold that there...

Findings explain unusual properties, but complicate search for universal theory Over the last quarter century, scientists have discovered a handful of materials that can be converted from magnetic insulators or metals into "superconductors" able to carry electrical current with no energy loss-an enormously promising idea for new types of zero-resistance electronics and energy-storage and transmission systems. At present, a key step to achieving superconductivity (in addition to keeping the...

3D Microchip Moves Data In All Directions
2013-01-31 05:17:11

redOrbit Staff & Wire Reports - Your Universe Online Scientists from the University of Cambridge have created, for the first time, a new type of microchip that allows information to move in three dimensions -- from left to right, back to front, and top to bottom. The breakthrough could allow a many-fold increase in performance compared with current microchips, which can only pass digital information in two dimensions - from either left to right or front to back. Researchers...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
