Definition of BCS theory

: 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.
