How Are Quantum Numbers Derived from the Schrödinger Equation?

AI Thread Summary
Quantum numbers n, l, and ml are derived from solving the Schrödinger Equation (SE) for bound systems, with each set corresponding to a specific wave function. The discussion highlights that fine structure arises from the energy splitting between spin states (up and down) within orbitals. It is noted that in multi-electron atoms, electrons must be treated as indistinguishable fermions, leading to the concept of product states rather than individual electron states. The principle of the Pauli exclusion states that no two electrons can have the same set of quantum numbers. Overall, the derivation and implications of quantum numbers in atomic structure are complex and involve considerations of electron identity and spin.

let me see if I got this one right:

By solving the S E for bound system u got the quantum number n l and ml. each set of numbers corresponds to a curtain wave function and electron. One gots fine structure when adding the spin up 1/2 and down 1/2. so every electron in the atom has a set of these quantum numbers and no two electrons can have the same set.

thanx for your patience and replies

Yes, for V~1/r^2 at least.

Yes, in particular an eigenfunction of the Hamiltonian.

I'm not sure. Actually, I don't think so. I haven't ever treated multi-electron atoms too rigorously, but I think that, strictly speaking, the eigenstates would be product states that combine all electrons as fermions, rather than treating them individually. Since electrons are identical, it doesn't make quantum sense to speak of individual electrons in a multi-electron system.

There is an energy splitting between the spin up and spin down states of a given orbital.

Again, I think that the eigenstates of electrons in a multi-electron atom are actually products states, but I'm not sure.
 
Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'
(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
