A memory effect that is crucial in electronics has been seen for the first time in a cloud of ultracold atoms. The phenomenon represents a milestone in the emerging field of ‘atomtronics’, which seeks ...

Physicists at the University of Wisconsin–Madison directly measured, for the first time at nanometer resolution, the fluid-like flow of electrons in graphene. The results appear in the journal Science ...

In the first demonstration of its kind, researchers have controlled the spin of electrons using a ballistic technique -- bouncing electrons through a microscopic channel of precisely constructed, ...

If you want an electrical current to flow around a normal metal ring you have to supply enough energy to overcome the metal’s resistance – right? Not always, according to physicists in the US and ...

Artist’s impression of the quantum spin Hall effect in a graphene-based spintronic device, integrated in a chip. The blue and red spheres are spin-up and spin-down electrons traveling along the edge ...

A river made of graphene with the electrons flowing like water. Courtesy: Ryan Allen and Peter Allen, Second Bay Studios Electrons can behave like a viscous liquid as they travel through a conducting ...

Strange metals defy the 60-year-old understanding of electric current as a flow of discrete charges. (Nanowerk News) We all learned that electricity is caused by electrons moving in a metal. Each ...
