BCS theory
noun
ˌbē-ˌsē-ˈes-
: a theory in physics: electrons can combine into pairs (called Cooper pairs) at low temperatures in order to travel through superconductors without resistance
However, electrons normally repel each other, and some intermediary is required to induce them to pair. In the BCS theory the intermediary is a phonon, a vibration or ripple in the lattice of the crystal.
