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 ...

Electricity powers our lives, including our cars, phones, computers, and more, through the movement of electrons within a circuit. While we can't see these electrons, electric currents moving through ...

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 ...

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, ...

In nano-scale electronic circuits, the phenomenon of quantum interference between electrons can lead to states where electrons appear to split. Professor Mitchell said, "In a nanoelectronic circuit, ...

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 ...
