Would someone explain me superconductivity?

Click For Summary

Discussion Overview

The discussion revolves around the concept of superconductivity, specifically in the context of atomic physics and its relation to quantum physics. Participants seek explanations and insights into the nature of superconductivity and its properties.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant requests an explanation of superconductivity within the atomic framework, expressing concern about its relevance to quantum physics.
  • Another participant suggests that there is ample information available online, implying that a search could yield useful results.
  • A third participant provides a link to a Wikipedia article, highlighting that superconductors exhibit zero resistivity under certain conditions and suggesting that this indicates superconductivity is a thermodynamic phase with universal properties.
  • Repetition of the initial request for an explanation of superconductivity in the atomic world, along with a reference to a blog post that may provide additional guidance.
  • A participant expresses appreciation for the shared blog post, indicating it may help in addressing questions from newcomers to the topic.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the explanation of superconductivity, and multiple viewpoints regarding the availability of information and the nature of the topic are present.

Contextual Notes

Some participants reference external sources for information, which may contain varying levels of detail and perspectives on superconductivity. There is no resolution of the initial request for an explanation.

Who May Find This Useful

This discussion may be of interest to individuals seeking foundational knowledge about superconductivity, particularly in the context of atomic and quantum physics.

Would someone explain me superconductivity IN ATOMIC WORLD? if this doesn't belong in quantum physics I am sorry admin

Have you googled superconductivity? There is a lot of information out there for free.
 
Here is a reasonable explanation:

http://en.wikipedia.org/wiki/Superconductivity#Explanation

If you read further in other sections you'll find some interesting insights such as:

On the other hand, there is a class of properties that are independent of the underlying material. For instance, all superconductors have exactly zero resistivity to low applied currents when there is no magnetic field present or if the applied field does not exceed a critical value. The existence of these "universal" properties implies that superconductivity is a thermodynamic phase, and thus possesses certain distinguishing properties which are largely independent of microscopic details.

and see also "Theories of Superconductors' further along in the article.

VERY NICE. Thanks for posting that. It will save me numerous (internal) cuss-words in responding to lazy newbies.
