Discussion Overview

The discussion revolves around the validity of BCS theory in explaining superconductivity, particularly in the context of high-temperature superconductors versus conventional superconductors. Participants explore claims of the theory being disproven and its continued relevance in certain applications.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants assert that BCS theory has been disproven, citing credible sources like physicsweb.org or Scientific American.
  • Others question the definition of BCS theory and its applicability, suggesting that while it may struggle with high-temperature superconductors, it still adequately explains superconductivity in simpler materials.
  • A participant challenges the notion of BCS being disproven, arguing that it remains valid for conventional superconductors and that recent discoveries indicate a crossover between BEC and BCS regimes.
  • There is a call for participants to justify their claims and to better understand the BCS theory before making assertions about its validity.

Areas of Agreement / Disagreement

Participants express disagreement regarding the status of BCS theory, with some claiming it has been disproven while others defend its continued relevance and application. The discussion remains unresolved with competing views on the theory's validity.

Contextual Notes

Participants reference the limitations of BCS theory in explaining certain phenomena, particularly in high-temperature superconductors, but do not reach a consensus on its overall validity or applicability.

BCS theory has been disproven, though still people use it to explain things,that's all. No, I don't remember where I read it. It was a credible source though, physicsweb.org, or scientific american...

What is BCS again?

Maybe you are referring to the difficulty in explaining superconductivity in high-temperature superconductors by the BCS theory. However, this does not mean that BCS does not explain superconductivity in simple materials.

No, it was something else. I don't remember.

Well then, this is all useless since you are simply throwing things out without justification, the same way you somehow got the idea that "phonons" must accompany any pair anhillation.

Go study what exactly is the BCS theory, and then look at why it is STILL being used in conventional superconductors, and why extension to it is still valid for LHe condensation. In fact, the recent discovery of the Fermionic condensation shows that there is a smooth crossover between the regimes of BEC and BCS. So it would be hilarious to say that BCS has been "disproven".
