Unique quantum material could enable ultra-powerful, compact computers

 Quantum Physics News
 20 May 2022
Information in computers is transmitted through semiconductors by the movement of electrons and stored in the direction of the electron spin in magnetic materials. To shrink devices while improving their performance—a goal of an emerging field called spin-electronics ("spintronics")—researchers are...

Electrons in a crystal found to exhibit linked and knotted quantum twists

 Quantum Physics News
 20 May 2022
As physicists delve deeper into the quantum realm, they are discovering an infinitesimally small world composed of a strange and surprising array of links, knots and winding. Some quantum materials exhibit magnetic whirls called skyrmions—unique configurations described as "subatomic hurricanes."...

Quasi-symmetry in CoSi reveals new type of topological material

 Quantum Physics News
 19 May 2022
Ever since the discovery of the quantum Hall effect (Nobel Prize 1985), symmetry has been the guiding principle in the search for topological materials. Now an international team of researchers from Germany, Switzerland, and the U.S. has introduced an alternative guiding principle, "quasi-symmetry,"...
