  Researchers have found that an atomic clock at the U.K.'s National Physical Laboratory (NPL) has the best long-term accuracy of any other clock in the world. Studies of the clock's accuracy show it is nearly twice as accurate as previously thought. The clock would lose or gain less than a second in about 138 million years. The NPL's CsF2 clock is a "caesium foundation" atomic clock, in which the "ticking" is provided by the measurement of the energy required to change a...

Quantum communication could be an option for the absolutely secure transfer of data. The key component in quantum communication over long distances is the special phenomenon called entanglement between two atomic systems. Entanglement between two atomic systems is very fragile and up until now researchers have only been able to maintain the entanglement for a fraction of a second. But in new experiments at the Niels Bohr Institute researchers have succeeded in setting new records and...

Material designed for energy applications is 10 times faster than natural enzyme, uses inexpensive metalsLooking to nature for their muse, researchers have used a common protein to guide the design of a material that can make energy-storing hydrogen gas. The synthetic material works 10 times faster than the original protein found in water-dwelling microbes, the researchers report in the August 12 issue of the journal Science, clocking in at 100,000 molecules of hydrogen gas every second.This...

Scientists at Berkeley Lab find nanoparticle size is readily controlled to make stronger aluminum alloysLong before they knew they were doing it "“ as long ago as the Wright Brother's first airplane engine "“ metallurgists were incorporating nanoparticles in aluminum to make a strong, hard, heat-resistant alloy. The process is called solid-state precipitation, in which, after the melt has been quickly cooled, atoms of alloying metals migrate through a solid matrix and gather themselves in...

Researchers find magnetic skyrmions in atomically thin metal filmPhysicists at Hamburg and Kiel University and the Forschungszentrum Jülich have found for the first time a regular lattice of magnetic skyrmions "“ cycloidal vortex spin structures of exceptional stability "“ on a surface. This fascinating magnetic structure was discovered experimentally at the University of Hamburg by spin-polarized scanning tunnelling microscopy and imaged on the atomic scale. Theoreticians at the...

A new source of very cold electrons will improve the quality and speed of nanoimaging for drug and materials development, to a trillionth of a second.The study published in Nature Physics today was carried out by researchers from the ARC Centre of Excellence for Coherent X-ray Science (CXS), headquartered at the University of Melbourne.Associate Professor Robert Scholten from the University's School of Physics  and the CXS, said the new cold electron source offered potential advances in...

Physicists from Juelich, Kiel and Hamburg identify an atomic-scale magnetic lattice of cycloidal vortices in a thin metal filmPhysicists at Forschungszentrum Jülich and the universities of Kiel and Hamburg are the first to discover a regular lattice of stable magnetic skyrmions "“ radial spiral structures made up of atomic-scale spins "“ on a surface instead of in bulk materials. Such tiny formations could one day form the basis of a new generation of smaller and more efficient data...

A violation of one of the oldest empirical laws of physics has been observed by scientists at the University of Bristol. Their experiments on purple bronze, a metal with unique one-dimensional electronic properties, indicate that it breaks the Wiedemann-Franz Law. This historic discovery is described in a paper published today in Nature Communications.In 1853, two German physicists, Gustav Wiedemann and Rudolf Franz, studied the thermal conductivity (a measure of a system's ability to...
