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 ...

Time to retire the old soldering iron? In the “atomtronic” circuits pictured on the right, it is atoms, not electrons, that flow. Such circuits could form the basis for ultra-sensitive gyroscopes.

Ballistic electrons are among the most fascinating phenomena in modern quantum materials. Unlike ordinary electrons, they do ...

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 ...

A river erodes its course. In an electric circuit, does the wiring get eroded by the current, atoms, electrons etc? — Bill "It's a reasonable analogy to think of an electric current acting like a flow ...

Key learning points Electrical charges What are free electrons? Cell polarity Conventional current direction Electrons orbit the nucleus. An atom has a neutral charge, because it contains the same ...
