Talk:Free field

context

I like the sophistication here, but this article needs some serious elaboration/explanation, and also some additional simpler material.

1. The classical section could be expanded. Am I wrong? - I think that there are simple examples of free fields such as EM or other travelling wave solutions?
2. Smeared fields?
3. Unitary irrep?
4. Elaborating on what $f$ and $g$ represent. (Edited --HappyDog271, 15:39, 6 June 2016 (GMT))
5. etcetera...

Are unbound particles free-field quantum solutions? The article could easily be twice as long if appropriate context/explanation were added.—The preceding unsigned comment was added by RichG (talk • contribs) .

Actually, feel free to expand as you see fit. I think this article has a lot of potential too. It's sort of nicely tucked away at the moment; I only found it through normal ordering. --HappyCamper 16:02, 4 September 2006 (UTC)[reply]

Writing style?

Just terrible!!! — Preceding unsigned comment added by Koitus~nlwiki (talk • contribs) 06:05, 24 December 2020 (UTC)[reply]
