A new phenomenon might make computing devices faster, smaller and much more energy-efficient. Moving so-called skyrmions needs 100,000 times smaller currents than existing technologies and the number of atoms needed for a ...

Clathrates are crystals consisting of tiny cages in which single atoms can be enclosed. These atoms significantly alter the material properties of the crystal. By trapping cerium atoms in a clathrate, scientists at the Vienna ...

Superconductivity is a fascinating quantum phenomenon in which electrons form pairs and flow with zero resistance. However, strong enough magnetic field can break electron pairs and destroy superconductivity. Surprisingly, ...

(Phys.org) —Sometimes mathematical theories have implications that extend far beyond their original purpose. This situation holds true for the four-color theorem, which was originally used by cartographers hundreds of years ...
(PhysOrg.com) -- Although most materials change shape in the presence of a magnetic field, the change is usually very small. In a new study, scientists have found that a certain magnet containing manganese experiences a change ...
For the first time, physicists have developed a technique that can peer deep beneath the surface of a material to identify the energies and momenta of electrons there.
