Talk:Electronic entropy

Quality Scale
Hello, I would like to formally rate the article on the WikiPhysics quality scale. I am being bold and saying that this article deserves somewhere between B and A. Given the relatively low importance of this topic in physics as a whole and its satisfactory development, I am willing to give it an A for now so that is does not catch too much attention. As I wrote this article, I am of course biased. If anyone feels this article deserves a lower rating, they should feel free to change the rating with my blessing!

To do:
At present, this article seems fairly complete for me; more information would likely lead to confusion without significant understanding. In addition, the relatively large amount of references to primary sources relative to the length of the article should be good enough for further study for the interested researcher.

Pi or pi squared
could you provide a page or a book section, I cannot find this expression in the Ashcroft-Mermin, if not I will have to revert it again until a better source is provided. --MaoGo (talk) 23:25, 25 February 2019 (UTC)


 * Yes, the page is listed on the reference I added. It is on pages 53 and 54. The result you want follows from equations (2.102) and (2.96).  Sorry for my clumsiness; this is my first Wikipedia edit.
 * in those pages I see only specific heat not the electronic entropy. And the only mention is in the problem section. MaoGo (talk) 18:56, 26 February 2019 (UTC)MaoGo (talk) 18:54, 26 February 2019 (UTC)
 * The relationship between specific heat and entropy is in the second equality of equation (2.96). Since both the specific heat $$c_v$$ and the entropy $$s$$ are linear in temperature, this equation implies that they have to have the same leading coefficient.
 * If it helps, there is an equivalent discussion in Abrikosov's book Fundamentals of the Theory of Metals, in the vicinity of equation (2.28).
 * I agree, I have just never seen the electronic entropy explicitely written as in this article. I hope we can find a more direct source. --MaoGo (talk) 20:16, 26 February 2019 (UTC)
 * If you really want a completely direct use of this equation, you can find it in equation (7) of this paper: http://advances.sciencemag.org/content/4/5/eaat2621. But I personally would not cite this over a textbook.
