If I were able to transform the Hamiltonian into terms that all commute with Lz would it be fine just to consider the system as an arbitrary |n, l, m> system?
Hey, I just had a quick question about using hamiltonians to determine energy levels.
I know that the eigenvalue of the hamiltonian applied to an eigenket is an energy level.
H |a> = E |a>
But my question is if I am given an equation for a specific Hamiltonian:
H = (something arbitrary)
And...
