Mechanism of high-temp. superconductors

Click For Summary
SUMMARY

The discussion centers on the mechanisms behind high-temperature superconductors, specifically addressing the limitations of the Bardeen-Cooper-Schrieffer (BCS) theory. Participants emphasize that the phenomenon of superconductivity at temperatures exceeding 25 Kelvin remains an unresolved question in the field. The consensus indicates that alternative theories beyond BCS are necessary to explain this behavior in certain materials.

PREREQUISITES
  • Understanding of superconductivity principles
  • Familiarity with Bardeen-Cooper-Schrieffer (BCS) theory

My prof. asked: "What is the mechanism that causes certain materials to exhibit superconductivity at temperatures much higher than around 25 kelvin?"
then until now it remain a question to me?.. so anyone have an idea? thank you.

This is still an open question, so why should your prof ask if he ignores the answer? The best answer is "not BCS".
