BCS theory explains superconductivity through Cooper pairs of electrons
The BCS theory describes superconductivity as a microscopic effect caused by a condensation of pairs of electrons known as Cooper pairs. These pairs move through the lattice without resistance. The theory was proposed by John Bardeen, Leon Cooper, and John Robert Schrieffer in 1957.
Example
In conventional superconductors, BCS theory explains phenomena like the Meissner effect, where a material expels magnetic fields when cooled below its critical temperature.
Understanding BCS theory is crucial for explaining and predicting the behavior of conventional superconductors.
