An international group of physicists has traced the origin of an electromagnetic interaction to the Dirac equation, a fundamental equation of quantum physics.
How small can a droplet shrink and remain a liquid?
Physicists have wondered in recent years if they could control how atoms interact using light. Now they know that they can, by demonstrating games of quantum billiards with unusual new rules.
Electron microscopy at the Department of Energy's Oak Ridge National Laboratory is pointing researchers closer to the development of ultra-thin materials that transfer electrons with no resistance at relatively high temperatures.
Just as in the well-known children's story of Goldilocks and the Three Bears, something good happens when things are done in moderation, rather than in extremes.
Researchers at Chalmers University of Technology shows that applying a moderate in-plane magnetic field increases spin lifetime of electrons in graphene. The results of this work have profound implications for graphene's ...
An experiment at Tohoku University (Japan) in 2008 laid the foundations for research on 'spin caloritronics' – a field that aims to develop more effective and energy-saving data processing in information technology. Since ...
