- TL;DR Summary
- So what I don't quite understand, is how direct products in Quantum mechanics can be acted upon with operators. Specifically spin up and spin down states, which I believe are (1,0) and (0,1) vectors.
Now when we have an H atom, we have a proton and electron, so the wavefunction now is the direct product of the spin states of electron and proton. Assuming these are (0,1) and (0,1), so both are in down state, what does the direct product look like? (0,1,0,1)?
And when we act on such a direct product with the sigma (Pauli) matrices, and sigma+ and sigma-, we act on the individually, is that right?
Thank you!
PS. this is NOT homework help, term hasnt even started and this is a past question sheet. Also, I have answers, but they are brief and incorrect.
THANK YOU! :)
