comment Mnemonic for creation and anhiliation operators
That's a good idea. I always thought of the dagger as a dagger, which kills something.

Does the $\otimes$ behave like a product? So $\alpha |a\rangle \otimes \beta |b\rangle = \alpha\beta (|a\rangle \otimes |b\rangle)$?

Why is the last equality sign true?

Found another one. See page 7. Are they both wrong?

I think this is the source where our professor copied the results. A colleage just pointed me to this paper, see forumla 20, which has the correct values. Or are they doing the same mistake as I did? (You have to right-click, select "Save as..." and open the PDF, their webserver is misconfigured)
