Concept

Cooper pair

A molecular structure resembling a Cooper pair, with six spheres connected by lines, symbolizing the weak binding of two electrons at low temperatures within a metal lattice.

A state in which two electrons, which normally repel each other, become weakly bound together at low temperatures. As one electron moves through a metal lattice, it slightly displaces the positive ions, creating a transient positive charge that attracts the second electron. Operating as a pair, the electrons act as a single boson, allowing them to flow through the metal without resistance.
