Talk:Higher order coherence

How is this different than Coherence (physics)

I'm tempted to request this be merged into the article on Coherence (physics), as a brief scan of both tell me they're covering a lot of the same material. Bibekbabupokharel, can you explain why this concept should be treated in a separate article? ~ ONUnicorn^{(Talk|Contribs)}problem solving 21:14, 18 August 2016 (UTC)

What is 'stellar light'?

This is mentioned for g(2), without explanation or reference. Suposedly, is has a gaussian decay of second order coherence. Nonetheless, the formula explicitly given in the main text describes exponential decay! — Preceding unsigned comment added by Wouterretuow (talk • contribs) 10:09, 29 November 2018 (UTC)

Title

The title is capitalized and I believe that this is wrong and forbidden by the wikipedia manual of style 2804:431:C7E2:F7DC:4030:9377:F4D4:FC45 (talk) 15:38, 17 August 2020 (UTC)

I have moved Orders Of Coherence into Higher order coherence (due to bad title). Now, I propose merging Degree of coherence into Higher order coherence. I think the content in Degree of coherence can easily be explained in the context of higher order coherence, and a merger would not cause any article-size problems in here. Degree of coherence has very few citations so it is not going to be difficult to merge. ReyHahn (talk) 08:37, 14 March 2023 (UTC)

I support your proposal.

However a reader of Coherence_(physics)#Mathematical_definition might reasonably expect that following the link Further information: Degree of coherence would lead to further information on the mathematical definition, esp. since the content in the main Coherence page is intelligible only to an expert.

My first reaction as a non-expert to "Higher order coherence" is "higher than what?" I would expect an article titled "Orders of coherence" or maybe "Coherence orders".

I think this Higher Order page would benefit from reorganization: move Young up and call it "Example of first order coherence"

Then Hanbury Brown and Twiss as "Example of second order coherence". Then Definition. This kind of ramp gives a non expert a chance to get something of the idea of "order of coherence" before a barrage of formulas. Johnjbarton (talk) 01:13, 8 June 2023 (UTC)

I agree, both articles have to be merged into 1, the organization of Degree of coherence is better but Higher order coherence is better cited. As for the name I do not have any strong feelings, but I do see a problem with "higher order coherence", while also explaining first order coherence. If not we can go for "Coherence order".--ReyHahn (talk) 17:40, 8 June 2023 (UTC)

I had a chance read Glauber's 1963 paper to try to fix up Coherence_(physics)#Quantum_coherence. Based on that I strongly support your merger.

Ideally the #Quantum_coherence section will be a summary pointing to your merger. (It's just a kinda muddley hodge-podge now). Johnjbarton (talk) 03:13, 13 June 2023 (UTC)
