Discussion Overview

The discussion revolves around a homework problem related to finding eigenvalues in quantum mechanics, specifically involving a projection operator as its potential. Participants express their experiences and challenges with the problem, as well as their perceptions of the knowledge level of responders in the homework section.

Discussion Character

  • Homework-related
  • Debate/contested

Main Points Raised

  • One participant notes that the original thread was moved to the homework section, suggesting that the move was reasonable but expressing concern about the knowledge level of responders in that section.
  • Another participant challenges the claim that responders lack knowledge of quantum mechanics, asserting that there were several responses and that the problem is complex due to the projection operator involved.
  • A third participant expresses uncertainty about the physical states of the potential in the problem, indicating that they are still working through the issue.
  • A later reply acknowledges a misunderstanding regarding the knowledge of responders and thanks the community for their input.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the knowledge level of responders in the homework section, with some asserting that there is sufficient expertise while others express doubt. The discussion remains unresolved regarding the specifics of the problem itself.

Contextual Notes

There is mention of issues with LaTeX formatting in the discussion, which may affect the clarity of mathematical expressions. Additionally, the complexity of the problem due to the projection operator is highlighted, indicating potential challenges in finding a solution.

This thread, https://www.physicsforums.com/showthread.php?t=74810, was orignally posted here in the QM forum, but it was moved to the homework section, which is reasonable. But nobody there knows quantum mechanics. I guess the OP gave up on it, but I'm curious how to do the problem now. So if somebody could take a look at it that would be cool. I guess you should reply in the homework section and not to this post directly.

thanks

What do you mean that nobody there knows quantum mechanics?

There were several responses, and from what I've seen, I certainly cannot say that those responders did not know QM.

The problem isn't easy due to the projection operator as its potential. You need someone willing to grind it out to work through this. It has nothing to do with people not knowing QM. Almost everyone who reads this section also read the Homework section.

I'm giving my best shot.So far,i think that the potential doesn't have physical states.

EDIT:I'll take a break.Apparently,there's something wrong with the LaTex.I'll resume posting later on.

My mistake. Thanks everyone :)
