Quantum metals are metals where quantum effects—behaviors that normally only matter at atomic scales—become powerful enough to control the metal's macroscopic electrical properties. Subscribe to our ...

For the first time, researchers in China have demonstrated a high-temperature superconducting diode effect, which allows a supercurrent to flow in both directions. Published in Nature Physics, the ...

A practical method for mapping the flow of a current in devices with complex geometries that could be used to optimize circuit design has been developed at KAUST. A traditional high-school physics ...

Superconductors are the key to lossless current flow. However, the realization of superconducting diodes has only recently become an important topic of fundamental research. An international research ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

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 ...

Researchers explain why weak magnetic fields can instantly control electrical flow direction in these quantum metals. (Nanowerk News) Quantum metals are metals where quantum effects—behaviors that ...
