Force of interaction between magnetic particles grows stronger with increasing distance An experiment has confirmed that spinons, particle-like magnetic excitations, can be confined in a magnetic insulator similar to the way elementary quarks are confined within individual protons and neutrons. The finding, in a well-described magnetic system, may offer new ways to explore Quantum Chromodynamics, the theory that describes the fundamental interactions of quarks. The observations of spinon...

Physicists at the National Institute of Standards and Technology (NIST) have demonstrated the first "universal" programmable quantum information processor able to run any program allowed by quantum mechanics"”the rules governing the submicroscopic world"”using two quantum bits (qubits) of information. The processor could be a module in a future quantum computer, which theoretically could solve some important problems that are intractable today. The NIST demonstration, described in...

Does your laptop sometimes get so hot that it can almost be used to fry eggs? New technology may help cool it and give information technology a unique twist, says Jairo Sinova, a Texas A&M University physics professor. Sinova and colleagues from Hitachi Cambridge Laboratory, Institute of Physics ASCR, University of Cambridge and University of Nottingham have had their research published in the renowned journal Nature Physics. Laptops are getting increasingly powerful, but as their sizes...

Researchers of Eindhoven University of Technology and the Radboud University Nijmegen in The Netherlands show for the first time why ordinary graphite is a permanent magnet at room temperature. The results are promising for new applications in nanotechnology, such as sensors and detectors. In particular graphite could be a promising candidate for a biosensor material. The results will appear online on 4 October in Nature Physics. Graphite is a well-known lubricant and forms the basis for...

Researchers at Ben-Gurion University of the Negev have developed thin films that exhibit carrier multiplication (CM). This development is of great interest for future solar cells. The films were synthesized at BGU by Prof. Yuval Golan and PhD student Anna Osherov of the Department of Materials Engineering and the Ilse Katz Institute for Nanoscale Science and Technology. The letter was published this week in Nature Physics. One of the important factors limiting solar-cell efficiency is that...

Even Albert Einstein might have been impressed. His theory of general relativity, which describes how the gravity of a massive object, such as a star, can curve space and time, has been successfully used to predict such astronomical observations as the bending of starlight by the sun, small shifts in the orbit of the planet Mercury and the phenomenon known as gravitational lensing. Now, however, it may soon be possible to study the effects of general relativity in bench-top laboratory...

Exquisitely sensitive microwave amplifier increases nano-scale measurement accuracy; could lead to quantum computing breakthroughs In the weird world of quantum mechanics, sub-atomic particles such as electrons and photons behave in strange ways that make no sense on the human scale. One of the counter-intuitive concepts of quantum mechanics is the uncertainty principle, which says that you can't pin a particle down. That means at any given moment, you can't know exactly both a particle's...

Scientists at the Naval Research Laboratory (NRL) have proposed theoretical models to explain the normal magnetic properties in iron-based superconductors. This research was published in the December 21, 2008 issue of Nature Physics. Their research builds on earlier research they conducted proposing a theoretical model for superconductivity in newly discovered iron-based superconductors. That earlier research was published in Physical Review Letters.To set the stage for the NRL researchers'...

Researchers at Uppsala University and Harvard University have collaboratively developed a new theoretical model to explain how proteins can rapidly find specific DNA sequences, even though there are many obstacles in the way on the chromosomes. The findings are being published today in the scientific journal Nature Physics. In living cells, DNA-binding proteins regulate the activity of various genes so that different cells carry out the right tasks at the right time. For this to work, the...

A new imaging technique developed by researchers at the University of Illinois overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom (less than one hundred-millionth of a centimeter). Optical and electronic properties of small assemblages of atoms called quantum dots depend upon their electronic structure "“ not just what's on the surface, but also what's inside. While scientists can calculate the...
