Researchers Develop 'Spinning Trap' To Measure Electron Roundness
2013-12-05 19:47:47

National Institute of Standards and Technology (NIST) JILA researchers have developed a method of spinning electric and magnetic fields around trapped molecular ions to measure whether the ions' tiny electrons are truly round—research with major implications for future scientific understanding of the universe. As described in the Dec. 6, 2013, issue of Science, the JILA team used their new spinning method to make their first measurement of the electron's roundness—technically, the...

Wormholes Driving Quantum Entanglement
2013-12-04 15:25:47

John P. Millis, PhD for redOrbit.com - Your Universe Online One of the strangest consequences of quantum theory, is what happens when elementary particles are created in pairs. These individual charges become entangled with their counterparts. The result is that interactions with one of these particles creates direct consequences for the other, even if the other particle is on the other side of the Universe. The simplest example of this is when an electron and positron are created when...

X-rays Reveal Another Feature Of High-temperature Superconductivity
2013-11-25 08:20:57

European Synchrotron Radiation Facility Discovery of a giant resonance puts these materials further apart Classical and high-temperature superconductors differ hugely in the value of the critical temperatures at which they lose all electrical resistance. Scientists have now used powerful X-rays to establish another big difference: high-temperature superconductivity cannot be accounted for by the mechanism that leads to conventional superconductivity. As this mechanism called...

Exploiting Flaws In Diamond Fragments Paves Way For Nanoscale MRI
2013-11-25 08:02:31

University of Cambridge By exploiting flaws in miniscule diamond fragments, researchers say they have achieved enough coherence of the magnetic moment inherent in these defects to harness their potential for precise quantum sensors in a material that is 'biocompatible'. Nanoscopic thermal and magnetic field detectors - which can be inserted into living cells - could enhance our understanding of everything from chemical reactions within single cells to signalling in neural networks and...

Study Could Lead To Paradigm Shift In Organic Solar Cell Research
2013-11-20 09:56:25

Stanford University Organic solar cells have long been touted as lightweight, low-cost alternatives to rigid solar panels made of silicon. Dramatic improvements in the efficiency of organic photovoltaics have been made in recent years, yet the fundamental question of how these devices convert sunlight into electricity is still hotly debated. Now a Stanford University research team is weighing in on the controversy. Their findings, published in the Nov. 17 issue of the journal Nature...

Advances in technology for computation and information storage always require to make the systems smaller and faster. The limits of miniaturization are those set by nature: Materials are composed by specific units, the atoms, that cannot be further divided. The question arising is: Can we still codify information at the atomic scale? And the answer is yes, we can! but one needs to manipulate a property of the atoms, individually, and keep them in that state there for sufficiently long time to...

Single-atom Bit Forms Smallest Memory In The World
2013-11-18 12:09:44

Karlsruhe Institute of Technology Control of the Magnetic Moment of Single Atoms Is the Key to Compact Data Memories and Quantum Computers One atom equals one bit: According to this design principle, we would like to construct magnetic data memories in the future. Presently, a compound of several million atoms is needed to stabilize a magnetic bit in a way that hard disk data are secure for several years. However, researchers from KIT have just made a big step towards a single-atom...

Grand Unified Theory Of Exotic Superconductivity?
2013-10-17 12:05:52

Brookhaven National Laboratory Scientists introduce a general theoretical approach that describes all known forms of high-temperature superconductivity and their "intertwined" phases Years of experiments on various types of high-temperature (high-Tc) superconductors—materials that offer hope for energy-saving applications such as zero-loss electrical power lines—have turned up an amazing array of complex behaviors among the electrons that in some instances pair up to carry current...
