Explanation as to how superconductivity works

Click For Summary

Discussion Overview

The discussion centers around the mechanisms of superconductivity, with participants seeking a technical explanation of the phenomenon. The scope includes theoretical aspects, particularly the Bardeen-Cooper-Schrieffer (BCS) theory, and its application to conventional superconductors.

Discussion Character

  • Exploratory, Technical explanation

Main Points Raised

  • One participant requests a detailed technical explanation of superconductivity.
  • Another participant emphasizes the vagueness of the request and suggests that a more focused inquiry based on prior research would yield better responses.
  • A third participant introduces BCS theory as a foundational concept for understanding conventional superconductors, mentioning specific materials like mercury and NbTi alloys.
  • The BCS theory is noted to operate within the framework of statistical field theory.

Areas of Agreement / Disagreement

Participants do not reach a consensus on how to approach the explanation, with some advocating for a more directed inquiry while others provide foundational concepts. The discussion remains unresolved regarding the best method to explain superconductivity.

Contextual Notes

The initial request lacks specificity, which may limit the depth of responses. The discussion also reflects varying levels of prior knowledge among participants.

Could someone give me a good explanation as to how superconductivity works. Feel free to be very technical.

Thanks :smile:

This is VERY vague. We can't teach you something that covers whole books.

In this age of web information, have you tried looking this up? What you have gathered on your own, and what did specific items did you not understand? This is a simple, more direct way for most of us to answer, rather than wanting a broad lesson.

Zz.
 


A good starting point would be to learn about BCS (Bardeen-Cooper-Schrieffer) theory, which explains superconductivity in "conventional" (critical temperature approximately Tc < 30 K) superconductors such as mercury (originally used by Kamerlingh Onnes in the discovery of superconductivity) and NbTi alloys (commonly used in applications).

The general field in which BCS-theory works is statistical field theory.
 


Thanks CompuChip, I will be sure to look into what you have said.
