BCS theory starts from the assumption that there is some attraction between electrons, which can overcome the Coulomb repulsion. In most materials (in low temperature superconductors), this attraction is brought about indirectly by the coupling of electrons to the crystal lattice (as explained above).
BCS: 50 Years is a review volume on the topic of superconductivity edited by Leon Cooper, a 1972 Nobel Laureate in Physics, and Dmitri Feldman of Brown University, first published in 2010.
Notes [ edit ] ^ According to, [ 4 ] superconductivity in Bi is not compatible with conventional BCS theory because the Fermi energy of Bi is comparable to the phonon energy (Debye frequency).
The complete microscopic theory of superconductivity was finally proposed in 1957 by Bardeen, Cooper and Schrieffer. [15] This BCS theory explained the superconducting current as a superfluid of Cooper pairs, pairs of electrons interacting through the exchange of phonons. For this work, the authors were awarded the Nobel Prize in 1972.
John Bardeen (/ b ɑːr ˈ d iː n /; May 23, 1908 – January 30, 1991) [2] was an American physicist.He is the only person to be awarded the Nobel Prize in Physics twice: first in 1956 with Walter Houser Brattain and William Shockley for their invention of the transistor; and again in 1972 with Leon Cooper and John Robert Schrieffer for their development of the BCS theory.

The Cooper pair state is responsible for superconductivity, as described in the BCS theory developed by John Bardeen, Leon Cooper, and John Schrieffer for which they shared the 1972 Nobel Prize. [2] Although Cooper pairing is a quantum effect, the reason for the pairing can be seen from a simplified classical explanation.
The BCS theory of superconductivity explains superconductivity as the result of the condensation of electric charges to Cooper pairs. In a dual superconductor an analogous effect occurs through the condensation of magnetic charges (also called magnetic monopoles). In ordinary electromagnetic theory, no monopoles have been shown to exist.
