University of California, Davis, researchers for the first time have looked inside gallium manganese arsenide, a type of material known as a "dilute magnetic semiconductor" that could open up an entirely new class of faster, smaller devices based on an emerging field known as "spintronics."
Visitors to Europe's largest multi-arts and conference venue will be invited to enter a virtual world and become an electrostatic force, where their energy controls the sounds and images in the room.
Matthew Tirrell probably has some idea of what pioneering physicist Albert A. Michelson experienced when University of Chicago founding President William Rainey Harper hired him in 1892 to build a physics department from scratch.
Researchers at the Department of Energy's Oak Ridge National Laboratory have found that nitrogen atoms in the compound uranium nitride exhibit unexpected, distinct vibrations that form a nearly ideal realization of a physics textbook model known as the isotropic quantum harmonic oscillator.
Bristol is spearheading a nationwide schools project to shed light on the origin of millions of cosmic rays that crash into the Earth’s atmosphere from outer space.
An international research group led by scientists from the University of Bristol and the Universities of Glasgow (UK) and Sun Yat-sen and Fudan in China, have demonstrated integrated arrays of emitters of so call 'optical vortex beams' onto a silicon chip. The work is featured on the cover of the latest issue of Science magazine, published tomorrow [19 October 2012].
Spintronic technology, in which data is processed on the basis of electron “spin” rather than charge, promises to revolutionize the computing industry with smaller, faster and more energy efficient data storage and processing. Materials drawing a lot of attention for spintronic applications are dilute magnetic semiconductors – normal semiconductors to which a small amount of magnetic atoms is added to make them ferromagnetic. Understanding the source of ferromagnetism in dilute magnetic semiconductors has been a major road-block impeding their further development and use in spintronics. Now a significant step to removing this road-block has been taken.
In the far future, superconducting quantum bits might serve as components of high-performance computers. Today already do they help better understand the structure of solids, as is reported by researchers of Karlsruhe Institute of Technology in the Science magazine.
At very low temperatures, close to absolute zero, chemical reactions may proceed at a much higher rate than classical chemistry says they should – because in this extreme chill, quantum effects enter the picture.
University of Adelaide applied mathematicians have extended Einstein’s theory of special relativity to work beyond the speed of light.
