What Are the Eigenstates and Energies of the Quantum Harmonic Oscillator?

Click For Summary
SUMMARY

The discussion focuses on determining the eigenstates and energies of the quantum harmonic oscillator described by the Hamiltonian H = (p²/2M) + (1/2)ω²r² - ω_z L_z. Participants clarify that eigenstates are represented as ψ(r) and that the corresponding energies E are solutions to the equation Hψ(r) = Eψ(r). The problem is framed in three dimensions, necessitating the conversion of angular momentum L_z and momentum p into spherical coordinates, similar to methods used in the hydrogen atom and isotropic 3D oscillator scenarios.

Homework Statement



Consider the Hamiltonian

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

Determine its eigenstates and energies.

2. The attempt at a solution

I want to check my comprehension; by eigenstate they mean

\psi(r)
from the good old

H\psi(r)=E\psi(r)
and then the energies would then be solutions for E?
 
Physics news on Phys.org
To sort of answer my own question the eigenstates would more properly probably be
|\psi>
in
H|\psi>=E|\psi>
 
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.
