BCS theory
Noun
Meaning
BCS theory (uncountable)
A theory for explaining superconductivity.
Examples
BCS theory relates the value of the critical field at zero temperature to the value of the transition temperature and the density of states at the Fermi level.
Conventional superconductors are materials that display superconductivity as described by BCS theory or its extensions.
However, the results of BCS theory do not depend on the origin of the attractive interaction.
The BCS theory, however, requires only that the potential be attractive, regardless of its origin.
This is incorporated into BCS theory, where lattice vibrations yield the binding energy of electrons in a Cooper pair.
