Breakthrough in coordinating electrons advances goal of quantum computing An international team of researchers including scientists at Princeton University have achieved a 100-fold increase in the ability to maintain control the spins of electrons in a solid material, a key step in the development of ultrafast quantum computers. Until recently, the best attempts at such control lasted for only a fraction of a second. But researchers Stephen Lyon and Alexei Tyryshkin have found a way to...

Measurements at the Vienna University of Technology deepen our understanding of quantum uncertainty Heisenberg's Uncertainty principle is arguably one of the most famous foundations of quantum physics. It says that not all properties of a quantum particle can be measured with unlimited accuracy. Until now, this has often been justified by the notion that every measurement necessarily has to disturb the quantum particle, which distorts the results of any further measurements. This, however,...

As electrons move past atoms in a solid, their charge distorts the nearby lattice and can create a wave. Reciprocally, a wave in the lattice affects the electrons motion, in analogy to a wave in the sea that pushes a surfer riding it. This interaction results in a thermoelectric effect that was first observed during the 1950´s and has come to be known as phonon-drag, because it can be quantified from the flow of lattice-wave quanta (phonons) that occurs over the temperature gradient....

Rotating magnetic moments: Applied Physics Letters reports Bochum's physicists led by Prof. Dr. Hartmut Zabel have demonstrated the spin pumping effect in magnetic layers for the first time experimentally. The behavior of the spin pumping had previously only been predicted theoretically. The research team at the RUB has now succeeded in measuring the effect using ultrafast X-ray scattering with picosecond resolution. Through their rotation of the magnetic moments, the so-called magnetic...

By combining two frontier technologies, spintronics and straintronics, a team of researchers from Virginia Commonwealth University has devised perhaps the world's most miserly integrated circuit. Their proposed design runs on so little energy that batteries are not even necessary; it could run merely by tapping the ambient energy from the environment. Rather than the traditional charge-based electronic switches that encode the basic 0s and 1s of computer lingo, spintronics harnesses the...

Researchers find magnetic skyrmions in atomically thin metal film Physicists at Hamburg and Kiel University and the Forschungszentrum Jlich 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...

Physicists from Juelich, Kiel and Hamburg identify an atomic-scale magnetic lattice of cycloidal vortices in a thin metal film Physicists at Forschungszentrum Jlich 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...

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...

A gyroscope uses the principles of conservation and angular momentum to measure and maintain orientation. The mechanical gyroscope is a spinning wheel or disk whose axle is free to take any orientation. The gyroscope's high rate of spin allows for large angular momentum which makes the orientation changes much more responsive to a given external torque. There is also the electronic, microchip-packaged MEMS gyroscope, solid state ring laser and fiber optic gyroscope, as well as the extremely...
