A new experiment offers the cleanest proof yet for magnetism-driven transitions of metals to insulators. Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying ...

In a carefully controlled environment, physicists have managed to stabilize a rare and previously short-lived phase of matter by using a simple method of rapid heating and cooling. This breakthrough ...

Ohm’s law is well-known from physics class. It states that the resistance of a conductor and the voltage applied to it determine how much current will flow through the conductor. The electrons in the ...

Researchers have identified a material that behaves as a conductor and an insulator at the same time, challenging current understanding of how materials behave, and pointing to a new type of ...

The performance of an object that has been dependent upon whether the object is composed of a conductive or a nonconductive material. Conductors are materials that allow electrons to flow freely from ...

University of Cambridge researchers have discovered that a material already known for its peculiar electrical properties appears to behave as both a conductor and an insulator at the same time. This ...

Extremely brief and intense laser pulses can switch fused silica (quartz) from an insulator to a conductor and back again within quadrillionths of a second. Semiconductors owe their name to their ...

Fran: You might be thinking that a conductor stands at the front of an orchestra waving their arms around, and they do. But we're talking about a different kind of conductor. A conductor of ...
