Talk:Weyl semimetal

Weyl fermions as elementary particles

According to the Standard Model all of the observed fermions are actually Weyl fermions. Left-handed and right-handed fermions combine to create a Dirac fermion by Yukawa interactions with the Higgs boson. While experimentally non of those particles is observed to be massless due to the Higgs mechanism, weak force parity violation is explained by the Dirac fermions being quasi particles created from elementary Weyl fermions. I believe the opening paragraph should mention it. — Preceding unsigned comment added by EitanTs (talk • contribs) 11:35, 30 July 2015 (UTC)

What is the main topic of this article?

The title is "Weyl semimetal", but the first sentence only mentions and defines "Weyl fermions". The semimetal is only mentioned at the end of the WP:LEDE, and only by giving a specific chemical example of it rather than actually saying what it is. If the article is supposed to be about the semimetal, the first sentence needs to begin with that and define it directly. Or, if the article is supposed to be about the fermion, then it needs to be moved to that title. DMacks (talk) 03:16, 11 January 2017 (UTC)

Agree. The whole article meanders on and off topic and could do with at least substantial reorganization. Ideally, though, I think there should be separate articles for the Weyl fermion (currently redirects to this article) and the Weyl semimetal. If I am to be trusted, the domain of the former is properly high-energy / particle physics, while the domain of the latter is a fairly recent condensed matter physics. The recent interest in these Weyl semimetal systems is in large part due to the fact that they present a kind of high energy physics in a condensed matter system, but the historic thread of each field is really quite separate.

This article is impossible to understand for someone without an advanced physics or math background

I am a Ph.D., albeit in inorganic chemistry. I found this entry very difficult to read and I could not understand the topic based on what was here. I suppose it would be hopelessly nebulous for a layperson without an advanced science education.

I came here looking for more information on Weyl Semimetals after reading about them in an article on axions making its way around the internet. An expert needs to review this and provide either a simple-language summary, a layperson summary, or review the text here and edit in a fashion that links to the complicated terminology it uses or simplifies this discussion.

Regardless of the decision it is in dire need of editing to fix the meandering main topics. I should not open an article on "Weyl Semimetals" and have a first sentence that reads "Weyl Fermions are..." I read that and immediately questioned what a Fermion is. This is a huge problem. — Preceding unsigned comment added by 71.145.217.237 (talk) 13:02, 23 November 2019 (UTC)
