To free electrons, something has to make them whirl fast enough to break away from their nuclei.

为了释放电子，必须使电子高速旋转而足以摆脱它们的原子核。

To build their desktop Big Bang, the researchers arranged strips of acrylic and gold so that laser light hitting the gold excites waves of free electrons called plasmons.

Normally, an incoming electron would have a good chance of displacing one of these low-energy incumbents, but unlike the free electrons in metals, which are usually singletons, those in a superconductor tend to wander around in pairs.
