FAQ
Frequently Asked Questions
It stands for the surnames of the three physicists who developed the theory: John Bardeen, Leon Cooper, and John Robert Schrieffer.
Yes, it remains the accepted microscopic theory for explaining conventional, low-temperature superconductivity.
In BCS theory, a Cooper pair is a pair of electrons with opposite momentum and spin that bind together via lattice vibrations (phonons), allowing them to move without resistance.
No. It successfully explains 'conventional' superconductors but does not fully explain the mechanism behind 'high-temperature' superconductors discovered later.
