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 ...

Electric current comes in many forms: current in a wire, flow of ions between the plates of a battery and between plates during electrolysis, as arcs, sparks, and so on. However, here on Hackaday we ...

In graphene, electrons move in strange ways. Their unusual and fluid-like behavior was observed by scientists at the National Graphene Institute, leading to a new wave of studies related to the ...

Physicists used to think that superconductivity -- electricity flowing without resistance or loss -- was an all or nothing phenomenon. But new evidence suggests that, at least in copper oxide ...

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.

Electrons in graphene can act like a perfect fluid, defying established physical laws. This finding advances both fundamental science and potential quantum technologies. For decades, quantum ...

Researchers from the Indian Institute of Science’s Department of Physics, together with researchers from Japan's National Institute for Materials Science, have finally discovered the quantum fluid of ...
