Noun
BCS theory (uncountable)
A theory for explaining superconductivity.
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. Source: Internet
Conventional superconductors are materials that display superconductivity as described by BCS theory or its extensions. Source: Internet
However, the results of BCS theory do not depend on the origin of the attractive interaction. Source: Internet
The BCS theory, however, requires only that the potential be attractive, regardless of its origin. Source: Internet
This is incorporated into BCS theory, where lattice vibrations yield the binding energy of electrons in a Cooper pair. Source: Internet
