Talk:List of states of matter

Superconductor?

Why do superconductors have their own state of matter on this page? Are'nt they just solids with some interesting properties, like zero resistance? — Preceding unsigned comment added by 50.5.106.186 (talk) 16:09, 24 September 2016 (UTC)

Transition from the non-superconducting to the superconducting state is a phase transition, and it involves discontinuities in thermodynamic properties and spontaneously broken symmetry just like e.g. liquid-solid transition. The only difference is that it happens between electrons in a solid, and not between atoms or molecules. It is thus justified to call it a state of electronic matter. Magnetic states (ferromagnetic, antiferromagnetic etc.) and the other states studied in condensed matter physics are similar and should also be added to the list.

Modern?

What does modern mean? Since when by what definition? On what authority? Idontusenumbers (talk) 10:14, 16 July 2020 (UTC)

Textbooks make that distinction, we just repeat it here. --mfb (talk) 14:17, 16 July 2020 (UTC)

Plasma uncommon on Earth?

The atmosphere is part of Earth, and lightning is common, so with lightning being plasma, I don't think plasma is uncommon on Earth.

Magnetoactive phase transitional matter

I'm trying to de-orphan Magnetoactive phase transitional matter should it be listed as a type of matter on this page? CT55555(talk) 02:20, 27 March 2023 (UTC)

Removed 'bosonic correlated insulator'

I removed the following text:

Bosonic correlated insulator: Consists of a crystal of excitons in a matter system. When excitons reach a certain density and light intensity, a bosonic correlated insulator is formed and an insulating effect is provided due to the excitons’ immobility. "What happened here is that we discovered the correlation that drove the bosons into a highly ordered state," According to Richen Xiong of the University of California, Santa Barbara. Bosons under ultracold temperatures usually form a condensate, but with both light and increased density and interactions at relatively higher temperatures, excitons organize themselves into a symmetric solid and an insulator with a neutral  charge.

I think this should only be re-added when there is an article about it. However, based on the research article, it is a kind of Mott insulator (but for bosons), so it could also be discussed in that article. Jähmefyysikko (talk) 15:07, 5 December 2023 (UTC)
