Quantum Spin Liquid Is A New State Of Magnetism
2012-12-21 09:38:33

redOrbit Staff & Wire Reports - Your Universe Online While experts had previously only confirmed the existence of two states of magnetism, experts from the Massachusetts Institute of Technology (MIT) report that they have been able to experimentally demonstrate the existence of a third kind. The MIT researchers have dubbed the new state a quantum spin liquid (QSL), and they describe their findings in this week's edition of the journal Nature. It joins ferromagnetism (the simple form...

While some theoretical physicists make predictions about astrophysics and the behavior of stars and galaxies, others work in the realm of the very small, which includes quantum physics. Such is the case at UC Santa Barbara, where theoretical physicists at the Kavli Institute for Theoretical Physics (KITP) cover the range of questions in physics. Recently, theoretical physicists at KITP have made important strides in studying a concept in quantum physics called quantum entanglement, in...

New Energy-efficient Computer Memory Developed Using Magnetic Materials
2012-12-17 10:57:08

University of California MeRAM is up to 1,000 times more energy-efficient than current technologies By using electric voltage instead of a flowing electric current, researchers from UCLA's Henry Samueli School of Engineering and Applied Science have made major improvements to an ultra-fast, high-capacity class of computer memory known as magnetoresistive random access memory, or MRAM. The UCLA team's improved memory, which they call MeRAM for magnetoelectric random access memory, has...

Chemical Processes Controlled With Ultra-short Laser Pulses
2012-12-12 16:29:32

Technische Universität Wien How can molecules be split in a controlled manner? A new experiment at the TU Vienna shows how research into ultra-short laser pulses can be combined with chemistry. Chemical reactions occur so quickly that it is completely impossible to observe their progress or to control them using conventional methods. However, new developments in electrical engineering and quantum technology enable us to achieve a more exact understanding and improved...

Potential for optoelectronics, solar cells, valleytronics and more When the dry lubricant, molybdenum disulfide, is stripped down to a single layer of atoms, a tightly bound quasi-particle comprised of two electrons and a hole forms with unique spin and valley properties, researchers from Case Western Reserve University and colleagues discovered. These charged quasi-particles, called negative trions, can be manipulated to change the light absorbed and emitted from this two-dimensional...

New research has demonstrated a way to make bismuth electrons and nuclei work together as qubits in a quantum computer. The discovery, published in Nature Materials, takes us a key step further to creating practical quantum computing which could tackle complex programs that would otherwise take the lifetime of the universe to finish. The collaboration partners are based in the University of Warwick, UCL, ETH Zurich and the USA Sandia National Labs. Information on our normal computers...

Researchers Build Graphene Switches

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.” Materials of this type might be used to read and write digital information not by using the electron´s charge, as is the case with today´s electronic devices, but by using its...

The Road To Spintronics Advances
2012-10-15 13:23:39

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...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
