Scientists
Alexey Abrikosov
Vitaly Ginzburg
Nobel Prize in Physics for pioneering contributions to the theory of superconductors and superfluids.
Lev Landau
The Ginzburg-Landau theories represent a significantly more ordered state of a superconductor at low temperatures compared to the normal state at temperatures above the SP junction.
Leon Cooper
John Schrieffer
John Bardeen
BCS theory:
Between the free conduction electrons of the material, except for the usual repulsive (Coulomb) forces there are attractive forces due to the polarization of the crystal caused by a moving electron.

The Meissner Effect
The transition of a substance to a superconducting state is accompanied by a change in its thermal properties
The Little–Parks effect, according to which the temperature of the transition of a thin-walled cylinder to a superconducting state periodically depends on the magnitude of the magnetic flux
Isotopic effect
London Moment
