Perturbing electron spins in a magnet usually results in excitations called "spin waves" that ripple through the magnet like waves on a pond that's been struck by a pebble. In a new study, Rice University physicists and their ...

Mott insulators are a peculiar class of materials with structures that should theoretically conduct electricity, but that are instead insulators. These materials contain strongly correlated electrons, which can generate highly ...
(Phys.org)—In 2015, scientists discovered a new magnetoresistance effect—that is, a new way in which magnetization affects a material's electric resistance—but hadn't yet found a promising application for the discovery, ...
(Phys.org) —Contrary to many textbook illustrations, electrons aren't just balls floating around an atom. In quantum theory, they're more like little tops, exhibiting "spin," and each creating its own tiny magnetic field.

Researchers at Delft University of Technology have recently carried out a study investigating spin-orbit interaction in Majorana nanowires. Their study, published in Physical Review Letters, is the first to clearly show the ...
Diamonds may be a girl's best friend, but they could also one day help us understand how the brain processes information, thanks to a new sensing technique developed at MIT.
