Visualizing the topology of electrons with '3D glasses'

They are seen as a beacon of hope for energy-saving electronics and the high-tech of the future: topological quantum materials. One of their properties is the conduction of spin-polarized electrons on their surface—even ...

Physicists mix classical light with half a photon on a qubit

A Russian-U.K. research team has proposed a theoretical description for the new effect of quantum wave mixing involving classical and nonclassical states of microwave radiation. This effect, which previously lacked a rigorous ...

Researcher increases speed and accuracy of sample analysis

A new description of electron scattering in the surface layers of samples proposed by the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw significantly speeds up materials analysis and enables ...

Unified theory for skyrmion-materials

Magnetic vortex structures, so-called skyrmions, could in future store and process information very efficiently. They could also be the basis for high-frequency components. For the first time, a team of physicists succeeded ...

Fermions exhibit collective behavior in unexpected situations

Some people like company. Others prefer to be alone. The same holds true for the particles that constitute the matter around us: Some, called bosons, like to act in unison with others. Others, called fermions, have a mind ...

Rice's 'quantum critical' theory gets experimental boost

New evidence this week supports a theory developed five years ago at Rice University to explain the electrical properties of several classes of materials -- including unconventional superconductors -- that have long vexed ...

Quantum teleportation analysed by mathematical separation tool

Scientists from the University of Vienna's Faculty of Physics in Austria recently gave a theoretical description of teleportation phenomena in sub-atomic scale physical systems, in a publication in the European Physical Journal ...
