B Commonly quoted PF article required.

[houlahound]

I lost all my download articles.

One article that has been attached a lot is a QM momentum analysis of a free wave on two slits.

It is a great highly readable article for non professionals.

I am thinking Bill or Peter Donis quote it a lot.

Please, please help me get this article back.

I can't remember author.

Free steak knife for first to link it.

I'll have a try.
http://quantummechanics.ucsd.edu/ph130a/130_notes/130_notes.html
or was it from a source you still know which. (And, no, I'm not after the knife.)

 

[houlahound]

It could be in there somewhere, the article was a single PDF from arix.

Showed how QM produced the double slit pattern with momentum eigenfunctions.

Raised to two steak knives.

That is def the topic and looks like a great paper but not the specific one, I will keep it tho.

Thanks.

 

[dextercioby]

Is it the one by Marcella?

 

[houlahound]

Is it the one by Marcella?

By golly that's it,

Thank you.

And now eerr about those steak knives...how can I say this.

Argh, and you were so lucky to loose it!

Argh, and you were so lucky to loose it!

Why, you don't like the paper??

I think it is a good step between undergraduate level and the main literature.

 

[vanhees71]

Well, they don't explain the handling of momentum- and position "eigenfunctions", and particularly in scattering theory (and the double-slit experiment is mathematically a scattering problem) that's the key issue to understand. Momentum and position "eigenfunctions" do NOT represent quantum states of a particle!

I rather recommend to first read the treatment in

A. Sommerfeld, Lectures on Theoretical Physics Vol. 4 (Optics)

There it's treated correctly. The very same mathematics applies to Schrödinger's equation.

Alternatively you can also have a look at the path-integral treatment in Feynman&Hibbs. That's a case, where the path-integral method is really elegant.

Do you have any links please.

 

[vanhees71]

The links are the books I mentioned!

Cheers, I was chasing free stuff, I did read a few excerpts. Books are so expensive not many by them without reading them on line first IMO.

As in steak knife?
