Excellent job!

Thank you for your excellent work! I enjoy it so much! The page provides a comprehensive overview of the concept of normalized solutions within the context of nonlinear Schrödinger equations. It effectively explains the mathematical background, the importance of normalization in quantum mechanics, and the specific condition for normalization. Additionally, the page includes references to key research papers, offering a solid foundation for readers seeking a deeper understanding of this topic. The explanations are clear and well-structured, making it accessible to those with a background in mathematics or physics. AzzurroLan (talk) 12:59, 12 July 2024 (UTC)

Quite nice!

Interesting!

The article on normalized solutions of the nonlinear Schrödinger equation provides a comprehensive exploration of key issues in this domain. Through rigorous mathematical derivations and clear physical explanations, it effectively demonstrates the significance and potential of normalized solutions in both theoretical frameworks and practical applications. By accurately addressing nonlinear terms, the study offers profound insights into the evolution of waves in complex systems, inspiring significant advancements in the field.--BK-L023 (talk) 14:03, 12 July 2024 (UTC)

This article has significant issues

To @77Davide77 and @JohnWYu, as well as their classmates (?) @AzzurroLan, @Daath3 and @BK-L023 who it seems reviewed this srticle.

This article has major problems. There is an established article on NLSE which has been around since 2005. It is only vaguely mentioned in the lede, never again. Wikipedia is not a set of isolated articles, it is many interweaved ones. What is not clear, and needs to be is to what extent the constraints is different. Also there must be better connections added to both. How this is notable and worth its own page rather than being a subsection of NLSE must also be demonstrated.

Thanks for the review. In fact, the normalized solution is not just in NLSE. It can be used for many problems in PDEs, such as the Dirac equation. So I don't think it's just as a subsection of NLSE. In recent years, hundreds of articles have been published on this subject, and Schrödinger's problem is probably the most dominantly studied one, so I'm bringing it up.

Do you have any suggestions for this change? Should I expand on Schrödinger's equation or just change the title to something like "normalized solution". JohnWYu (talk) 13:38, 15 July 2024 (UTC)

Your title limits it to NLSE. Adding the Dirac equation would digress, as would adding other PDE, you would need to change the title. A more general article on exploiting normalized solutions might work. However, you would need to do a fair bit of checking of what is already in other pages.

N.B., with a "real" quantum systems normalization is always required. Ldm1954 (talk) 13:52, 15 July 2024 (UTC)

Many thanks.I'll try to modify it. JohnWYu (talk) 14:34, 15 July 2024 (UTC)

Actually, what I wanted to show was the "normalized solution", but I wanted to describe it with a concrete example. That's why I added "NLSE" at the end. JohnWYu (talk) 13:48, 15 July 2024 (UTC)

I don't see a major step to improve the article to answer the issues I raised. Ldm1954 (talk) 20:55, 30 July 2024 (UTC)

Observations and suggestions for improvements

The following observations and suggestions for improvements were collected, following an expert review of the article within the Science, Technology, Society and Wikipedia course at the Politecnico di Milano, in July 2024.

The mathematics is correct. However, I would specify in the "Definition" section that the considered nonlinear Schrödinger equation is stationary, and I would use H^{1}(\mathbb{R}^{N}) (removing 0, although it is formally correct). The main issue of the article is the "History" section, in the part concerning the last 20 years. The subject is rather recent, involving a huge and increasing amount of specialised literature: maybe it is too early for a reasonable historical perspective.

Feedback from New Page Review process

I left the following feedback for the creator/future reviewers while reviewing this article: Weak article with many issues. Needs work from professionals, not students.
