Homework Help: Quantum Harmonic Oscillator

  1. Nov 2, 2011 #1
    1. The problem statement, all variables and given/known data

    Consider the Hamiltonian

    [tex]H=\frac{p^2}{2M}+\frac{1}{2}\omega^2r^2-\omega_z L_z[/tex]

    Determine its eigenstates and energies.

    2. The attempt at a solution

    I want to check my comprehension; by eigenstate they mean

    from the good old

    and then the energies would then be solutions for E?

    To sort of answer my own question the eigenstates would more properly probably be

    It's a three-dimensional problem, so the wave function will be a function of r, θ, and φ.

    Ah, right. (and just as I was getting comfortable in 2D)

    Convert L_z and p to spherical coordinates and separate variables just like in the H-atom case, or the isotropic 3D oscillator.
