Talk:Kondo effect

New Information

We now know more about the Kondo Effect, and this should probably be added to the article. More here: http://www-03.ibm.com/press/us/en/pressrelease/25152.wss 66.27.114.6 (talk) 22:25, 22 September 2008 (UTC)[reply]

What is C_m??

Why are wikipedia pages so prone to skipping explanation on bizarre constants or variables in equations? —Preceding unsigned comment added by 173.16.38.68 (talk) 03:16, 2 April 2010 (UTC)[reply]

In the original paper by Kondo it is named c, and is just a constant. Materialscientist (talk) 09:01, 2 April 2010 (UTC)[reply]

Please Simplify

This article needs a far more simplified section for the average reader. Tmangray 16:02, 14 March 2007 (UTC)[reply]

Resistance Minimum

Perhaps this needs to be emphasised over the divergent resistivity in the T=0 limit, since the resistance minimum was the experimental motivation for studying the problem, while the divergent resistivity is an artifact of the theory being non-perturbative.

Better Introduction

It should probably be stated at the beginning of the article that the Kondo phenomenon is what happens to electrons interacting with a magnetic impurity when the temperature is lowered, rather than starting with the resistivity and mentioning it later. Additionally, the Kondo effect is not resistivity's general dependence on temperature, but it is that there can be a minimum resistivity, which Kondo was able to explain and model mathematically.

Asymptotic freedom?

I think the discussion about asymptotic freedom is a little obscure. Asymptotic freedom means that the interaction gets weaker as the energy is raised, while the property of the interaction getting stronger at low energies and binding the quarks is generally called infrared slavery (or some other fancy names...). Of course, the two of them are related but the point in the Kondo effect is precisely the behaviour at low energies, the opposite regime to which asymptotic freedom refers.

Majorana Fermions in 2012???? What about the exact solution by Natan Andrei?

Ridiculous! There is a comment about the Kondo problem with Majorana zero modes (which, are currently barely even a discovery since only some of their properties have been confirmed), yet there is not a word on the fact that in the 80s Natan Andrei solved the problem exactly with the Bethe ansatz. Also, the citation for the Kondo effect in a quantum dot should include to the paper by David Goldhaber-Gordon, which measured it FIRST. Please correct these issues.... — Preceding unsigned comment added by 173.76.15.3 (talk) 00:32, 13 September 2017 (UTC)[reply]

duplicity

I would suggest merging the article with the article Kondo model under the name "Kondo effect". — Preceding unsigned comment added by Nayano2 (talk • contribs) 16:32, 18 March 2021 (UTC)[reply]

Spin-Flip Scattering

There should be a "Spin-Flip Scattering" page that redirects to here, because it is a very commonly used term.

History Section

In the history section, a statement is started in the second bullet point, which is never finished. Mattsil (talk) 13:31, 9 July 2024 (UTC)[reply]
